Shop Update 2019

By: Harris Mandell (Mechanical Engineering, ’21)


Some major changes to the Baja shop space have occurred over the past couple of months. This past August, a portion of the space in the Taylor Hall Instrument Machine Shop was restructured to accommodate more space for not only the Baja shop, but for a new welding cell, designed to benefit students and faculty all throughout the Hajim school. The welding cell contains an all new Siegmund welding table and fixturing kit. The team has been quick to take advantage of this new tool over the past couple of weeks during the frame fabrication process. The fixturing kit allows us to accurately align our frame tubes such that our finished frame will be dimensionally accurate to the model in CAD. 

The additional floor space in the Baja shop has also helped immensely for shop organization and for adding new pieces of equipment. John Miller, director of the Instrument Machine Shop, has been an integral part of this endeavor. With his help, we were able to sell some of our older pieces of machinery, replace them with some newer pieces, such as a Series I Bridgeport Mill and a horizontal band saw, and have the electrical wiring completed all before the start of the manufacturing season. The addition of these new machines and extra space has greatly increased our manufacturing capabilities and workflow in the shop. We’re very much looking forward to the rest of the season!

Midnight Mayhem 2019 Recap

By: Madeline Bedrock (Mechanical Engineering, ’21)


This year’s Midnight Mayhem was unlike any other, and boy was there a lot of mayhem. First, it was announced in late summer that the location of Midnight Mayhem was changing, so no longer were the nights of camping with a bunch of different teams and sharing the same row of porta potties. Rather than at Nickota Motocross Park like it has been in the past, it was moved to downtown Louisville at the Drop Forge Proving Grounds, the same location as Baja SAE Louisville will be in May. With this, the team ended up at a campsite twenty minutes away from the competition site that was completely different from the camping Baja is used to; this campsite had showers and real bathrooms! With this exciting news, Baja was ready to bring some new members to Midnight Mayhem and introduce them to what Baja is really like.

This year, we brought 12 new members, our 2017-2018 vehicle “Cali” and our new vehicle from this past season “Tennessee”, and ran into some familiar faces at Midnight Mayhem. At our usual stop at the Great Lakes Mall in Mentor, Ohio, we met up with Joyce Gray and Laura Loomis on behalf of Debbie and Mike George, Kevin Bonko’s family. They graciously bought food, drinks, and other snacks for the whole team, which was greatly appreciated. After leaving Mentor, we drove and made a stop at a Denny’s (thanks to Charles Patterson) just over the border into Kentucky for dinner, where we ran into no other than Kaven Marte (Chief Engineer ‘19). Additionally, when we made it to our campsite just after midnight, we ran into another old friend, Gilead Biggie (Chief Engineer ‘18). With some friendly faces and a bunch of new members, Midnight Mayhem was off to a great start.

It was a scorching 90 degrees and sunny on Saturday. Another shout out to Debbie and Mike George for stopping by during the day to talk Baja and bring the team needed sustenance that helped get us through the day. However, soon after when the endurance race began, true mayhem commenced. Throughout the course of the endurance race, Tennessee broke 2 sets of prototype aluminum steering links and A-arms, rod ends, and punctured a tire.  Cali on the other hand broke steering links, control links, and a steel A-arm (which we didn’t have a spare of, so we ended up welding a cup from an old left A-arm onto an old right A-arm to attempt to perform better in the race).  Because of all of the chaos that happened during the endurance race, we were not able to completely finish the race with both vehicles, but new members got to drive and have a fun experience.

Introducing the 2019-2020 Design Board

By: Madeline Bedrock (Mechanical Engineering, ’21)


Frame and Chassis

Team Lead: Ognjen Bosic

Ognjen Bosic is a sophomore, mechanical engineering major from Bosanski Samac, Bosnia and Herzegovina. This is his second year on the team, and he previously worked on the frame and chassis team.

Email: obosic@u.rochester.edu

The frame team is in charge of designing, testing, and manufacturing the chassis for the vehicle.  SolidWorks is used for the design and Siemens NX is used to perform finite element analysis and simulations of the different stresses on the chassis. In addition, the frame team collaborates with the data acquisition team to perform physical testing using strain gauges in order to validate the load cases calculated in the design programs.


Drivetrain

Team Lead: Daniel Troyetsky

Daniel Troyetsky is a junior, mechanical engineering major from White Plains, New York. This is his third year on the team, and he previously worked on the drivetrain team.

Email: dtroyets@u.rochester.edu

The drivetrain project team is responsible for powering the car. Typically, our vehicles run a CVT (Continuously Variable Transmission) from the engine to a double stage reduction gearbox attached directly to the wheels. We design and manufacture a new gearbox every year. We are also responsible for tuning the CVT once the car is complete to achieve maximum performance by balancing top speed, torque, and acceleration.


Suspension

Team Lead: Jaafar Al Hadab

Jaafar Al Hadab is a junior, mechanical engineering major from Al Mubarraz, Saudi Arabia. This is his third year on the team, and he previously worked on the suspension team.

Email: jalhadab@u.rochester.edu

The suspension is all hardware that connects the tires to the chassis, allowing for relative motion between the two. The design of a vehicle’s suspension is the determining factor in its handling characteristics; traits such as turning radius, role while turning sharply, or response to driving over an obstacle. To design and manufacture the suspension, the suspension project team makes use of a variety of CAD and finite element analysis tools (such as Siemens NX, SolidWorks, and Lotus Shark) as well as manufacturing techniques such as CNC machining, milling, lathing, and welding. Once the suspension has been built and mounted, the suspension team is responsible for tuning the suspension to the match our drivers’ preferred handling traits and terrain, as well as being ready to swiftly replace broken parts during a race.


Usability

Team Lead: Scott Smith

Scott Smith is a sophomore, mechanical engineering major from Ithaca, New York. This is his second year on the team, and he previously worked on the usability and brakes team .

Email: ssm115@u.rochester.edu

The Usability Project Team takes responsibility for every driver-to-vehicle system. Critical systems span from the brakes to the accelerator, and more. Leveraging ergonomics and performance, we extend to seating comfort and safety components. Drivers interact with all systems; the usability team regularly cooperates with other subsystems to complete our Baja vehicle.


Data Acquisition

Team Lead: Ethan Fahnestock

Ethan Fahnestock is a junior, physics major from Madbury, NH. This is his third year on the team and he previously served as the team’s electronics lead.

Email: efahnest@u.rochester.edu

The data acquisition team is responsible for collecting data from various systems of the car to validate the design choices of the vehicle in order to complete the design cycle. We also take care of communication at competitions using digital Motorola MOTOTRBO radios. Data is collected in different methods such as through Arduino products, strain gages, and more.


We can’t wait to see what they can implement this year!

Tribute to the Class of 2019

By: Madeline Bedrock (Mechanical Engineering, ’21)


This year, the team graduated four seniors: Kaven Marte, Rebeca Toro Garza, Marial Lara-Gutierrez, and Dylan Borruso. All these members dedicated huge amounts of time at U of R to Baja and we will miss them greatly this year. Here is a little about what our newly graduated seniors are up to!

Dylan Borruso, an optical engineering major, was on the team for three years at U of R, serving as Chief Mechanic for two of those years. He will soon be moving to Tulsa, Oklahoma to work for L3 Harris Technologies.

“Baja has helped me so much in understanding the design process and the manufacturability of parts.” – Kaven Marte

Kaven Marte, a mechanical engineering major, was on the team for all four years of college and served as the frame project team lead his sophomore year and the chief engineer during his senior year. He has just moved to Raymond, Ohio to work as a design engineer in the upper body division at Honda.

“I met incredible people at Baja that I know will be my friends for life. We are not just a team, but a family!” – Marial Lara-Gutierrez

Marial Lara-Gutierrez, a mechanical engineering major, was a part of the team for all four years of her college career. She served as the usability team lead for both her junior and senior year. She recently moved to Royal Oak, Michigan and we wish her the best in her job search!

“Baja was one of the best experiences of my college career. It helped me meet incredible people and gave me a set of tools that I will be able to use all of my life.” – Rebeca Toro Garza

Rebeca Toro Garza, a mechanical engineering major, was a part of the team all three years that she was at U of R. She served as the frame team lead during her junior year. She is currently in Boston for the summer before she moves to Stanford, California to pursue her PHD in mechanical engineering from Stanford University.

2019 Competition Results

By: Madeline Bedrock (Mechanical Engineering, ’21)


This year we attended the Tennessee and California competitions. In Tennessee, we finished:

  • 36th overall
  • 20th in acceleration
  • 41st in maneuverability
  • 62nd in sled pull
  • 40th in suspension
  • 47th in endurance

We also placed 4th in sales which is the best our team has ever performed. At this competition, we ran into tuning issues and because of inclement weather, all of the dynamic events and endurance took place on the same day. To read more about the complete results of the competition, please click here.

In California, we finished:

  • 43rd overall
  • 6th in sales
  • 12th in acceleration
  • 21st in hill climb
  • 27th in suspension
  • 58th in endurance.

 We also placed 6th in design with a score of 130 out of 150 points, the highest in our team’s history. This score could not have been possible without all of the hard work done by our team. Ethan Fahnestock, our electronics lead, and our electronics team made a major milestone by collecting large amounts of data throughout the season. With the data collected during testing, we were able to complete the engineering cycle which led to this significantly higher design score. We will be performing more tests this year as we will not be doing a full frame rebuild, so we hope to continue to improve with our design. Due to the muddy terrain faced during the endurance race, the suspension components did not hold up well and caused us to not be able to compete in the last third of the endurance race. To read more about the complete results of the competition, please click here.

We were also very happy to have several alumni attend the California competition(from left to right shown below): Laurence Lohman (Class of 2017), Chris Plunkett (Class of 2016), Nick Van Swol (Class of 2015 ), and Alan Grier (Class of 2017). We’d also like to extend a special thank you to Laurence for acting as our faculty advisor for the event.  If you would like to attend a competition in the future, please email me at mbedrock@u.rochester.edu and we’d love to see you there!

THE CAR IS COMING TOGETHER!

By: Loren McDonald (Mechanical Engineering, ’20)


Here at the Baja Shop, we’ve been putting in work to make sure our car gets built well and on-time. Before winter break, we managed to make a lot of progress on the frame, but our team really wanted to ensure that we would meet our rolling chassis deadline of February 11th so that we have ample time to test and iterate our designs for this year’s vehicle. To help us meet that goal, Kaven Marte, our Chief Engineer, organized a group of team members to come back to campus before the end of winter break. Over the course of a few days filled with Baja, Baja, and more Baja, they were able to bend tubes and weld together a very large portion of the frame.

The weekend after the entire team returned to break, we continued to focus most of our energy on getting the frame manufactured. We have made even more progress, and as it sits now, the frame only has a few minor members left to be welded on. Better still, the last few frame members are all able to be welded on at a later time, so we are now free to continue moving forward with manufacturing and assembling other components of our car.

Currently, we are focusing on getting the suspension completed. Noah and his suspension group are following in Gaetan’s footsteps (see Frame section), and are finishing making fixtures to assemble and weld together our suspension components. The fixtures will allow us to lay out the steel and aluminum tubes that we’ll use for the suspension arms in such a way that they cannot move away from the desired positions. Like previous years, we are using a simple A-arm and H-arm geometry where the tubes that make the suspension arms are laid out in a shape that resembles an “A” in the front and an “H” in the back. Hopefully with Noah’s fixtures, we’ll be able to continue to exceed our expectations for tolerances this year. We’ve been working hard to be more precise with our manufacturing this year, and it’s definitely paid off.

While the frame and suspension teams have been busy in the shop, our other team members are working in parallel to get other components ready for assembly once our suspension is complete. Several new members have been working on getting tab drawings completed, and we have sent several to Paragon Steel Rule Dies to be cut with a waterjet in the next couple days. Every year, we have to weld about a hundred tabs to our vehicle in order to attach all the different assemblies, and thanks to the support of Paragon, we’ll be able to have these all cut and made in a matter of hours.

Also, several of our team members are learning to use the Mechanical Engineering Department’s brand new toy: a HAAS. With the HAAS we will be able to transform our designs into tool paths that the HAAS will use to cut parts to extreme precision. Currently, some people from Noah’s group are working at getting our first few uprights cut so that we’ll be ready to attach wheels to the car as soon as the suspension arms are complete.

And everything I’ve discussed so far only covers a small portion of what we’ve been working on. Our team is firing on all cylinders to meet our deadline this year. We have some people working on making a new seat for the car out of carbon fiber, we have people preparing to put strain gauges on the car to understand the loads in our frame, and we have our business group working hard to submit budgeting documentation to the school to secure our funding for next year. It’s a busy time in and around the Baja Shop, but one thing’s for certain, we’re making a lot of progress towards one of the best cars the team has ever built.

FEBRUARY SUSPENSION UPDATE

By: Loren McDonald (Mechanical Engineering, ’20)


As some of you saw at Noah’s recent design review, he has been working hard to design the lightest suspension system in UR Baja history. This year we are trying to implement as much aluminum as possible. Noah’s team has been doing Finite Element Analysis (FEA) of several different components and load cases to determine where aluminum will be strong enough to withstand the beating the suspension system takes while traversing a Baja course. Noah had determined through analysis that the upper section of the A-arms can be made of aluminum, and that it’s likely that the steering links can be made of aluminum as well. By replacing heavy, steel members of the suspension system, we can save several pounds from last year’s car.

Another one of Noah’s projects that wasn’t discussed in other sections of the newsletter is the custom rear hubs. Last year, we just purchased hubs from an ATV parts website, and several judges at competition asked why we were not using our own hub designs. To be fair, they had reason to be curious since we can design significantly better hubs that weight significantly less than the beefy hubs meant for ATVs. This year, Noah’s group designed custom rear hubs that will package better with the upright, and more importantly, are much lighter than the hubs that we could’ve purchased off the shelf. We wanted to design custom front hubs this year, but unfortunately they got put on the backburner in favor of other projects. That being said, we did complete some work on them, and next year the Baja team should expect to be running a full set of custom hubs thanks to the work done by Noah’s group this year.

FEBRUARY DRIVETRAIN UPDATE

By: Loren McDonald (Mechanical Engineering, ’20)


Of all the groups, drivetrain is probably the most ahead in terms of manufacturing. Charlie held the first of our design reviews in the fall, and from the responses he received at his meeting, he was able to improve and finalize several of his designs months ago. As I explained in the previous newsletter, Charlie is implementing a new tensioning system that uses rotational motion and a turnbuckle to tension our drivetrain system. Currently, he has manufactured all the necessary parts for this system, and his group is just waiting to attach them to the car.

The most recent manufacturing for the drivetrain has been the gears for our transmission. Thanks to our sponsor, Rochester Gear, we have been able to have these gears manufacturing to good tolerances. In the near future, another sponsor, Gleason, will be hobbing (adding teeth) to the gear. Once the teeth are added to the gears, Charlie and his group will be ready to assemble our gearbox.

Also, as a team, we’d like to address some of the most frequently asked questions we’ve had about our power transmission system.

  1. Does your car have a shifting transmission, and if so, how many gears does it have?
    1. We do not have shifting capability in our transmission in favor of being able to manufacture a much lighter transmission system. That being said, our team uses a Continuously Variable Transmission (CVT) that uses a system of springs, weights, and pulleys to produce a range of gear reductions. When tuned, this allows our car to be operating at peak efficiency at all times
  2. Does your car have a reverse gear?
    1. Every year at least someone questions whether to add a reverse gear to our car. While some Baja teams have reverse gears, we have decided to not include one in favor of weight savings. Also, in many cases in this competition, if you have to reverse, you’ve already made a mistake and will be putting up a bad time. Since you get two chances at every event, we decided a reverse gear was not worth the weight.

Besides that, the only other thing Charlie’s group will be working on is breaking in the engine. As soon as we can get a weekend here in Rochester that isn’t freezing cold, we’ll be setting it up and getting it ready to power our finished vehicle.

FEBRUARY FRAME UPDATE

 

By: Loren McDonald (Mechanical Engineering, ’20)


This year one of our goals is to reduce our error during frame manufacturing. In previous years, our team has had some issues keeping the frame completely square, so this year, we worked with our adviser, Professor Muir, to solve this problem. After a few discussions, Gaetan designed several different fixtures to help us with manufacturing our frame. He used our CNC router to cut holes at specific locations in a piece of wood, and then he put short pieces of PVC in the holes to create fixtures that would lock the fame pieces in the correct position. By creating these fixtures, we have been able to ensure that our frame subassemblies are square and in-plane.

At the time of writing this, the frame group has just a few more members left to install. Gaetan has been working hard, and has managed to weld together all the frame subassemblies that were manufactured using his team’s fixtures. What’s really impressive about our frame manufacturing is that the last few members are all quick and easy ones. I wouldn’t be surprised if our frame is done before the end of January.

Because we have been able to get the frame (mostly) done in such a timely manner, we are hoping to be able to get some good strain gauge data to determine the forces in several frame members during test drives. Ethan and his electronics group are already working with Gaetan to determine which members we want to attach strain gauges to in order to get the most information about how forces are present in our frame.

FEBRUARY USABILITY UPDATE

By: Loren McDonald (Mechanical Engineering, ’20)


Quite possibly the biggest change to the Usability system of our vehicle this year is that we are going to be using a floor mounted pedal. After Midnight Mayhem, one of our new members, Scott Smith, was incredibly vocal about how his leg hurt after the race. After being inspired by his “immense pain and suffering,” (some sarcasm involved) Scott worked with Marial to design a floor mounted pedal that will hopefully be more comfortable for the driver. This year, Marial’s team is really hoping to make operating the vehicle as easy as possible so that the driver can focus more of their energy on the race.

 

Another interesting idea that Marial’s group is developing a wooden steering wheel. In many cases, wood is much lighter than a metal design, and wood is also a very durable material. Since the steering wheel is mostly safe from taking any sort of a beating from the racetrack, our team thinks a wooden steering wheel might actually be a great idea especially since we can easily use a CNC to manufacture the wheel. At the very least, it would be a unique design that would make us stand out.

 

Marial’s group is also making sure they are ready to start installing components as soon as the suspension is attached to our frame. They have been working with Professor Muir to create tool paths for various components to be made on the HAAS machine. Among these components is the brake pedal that is now ready to be assembled to the car as soon as possible.

 

The Usability team is not only making sure that all the components for the car are ready to be assembled, they are also making sure that we’re ready to drive. Marial’s group recently went through all our safety gear and threw out expired equipment, and some nasty, sweat-and-mud-stained fire shirts. We placed an order for new safety gear that just arrived, and so we are very ready and eager to drive this year’s car as soon as we are done in the next couple weeks.

FEBRUARY ELECTRONICS UPDATE

By: Loren McDonald (Mechanical Engineering, ’20)


Ethan and the electronics team have been busy working to improve our removable data collection box. What initially started out as just a hall-effect sensor for speed and RPM measurements has evolved into a much more developed tool for data collection. Ethan’s group has been working to add a GPS, an inertial measurement unit (IMU), and an analog-to-digital converter for other sensors that we use during data collection. In a few weeks, when we’re done with this year’s vehicle, the data collection box will be very useful for testing.

Currently, his team has been using the data collection box to work on some of our older vehicles. Ethan worked Marial and the usability group to use the data collection box to measure pressures in the brake line. Ethan’s group has also ironed out all the errors in the speedometer, so we now can get accurate, real-time speed readings for any of our vehicles by simply attaching a small box.

The electronics group has also been exploring some other sensors that might give us valuable data when it comes time to test and tune this year’s vehicle. They hope to be able to connect strain gauges to several members of our frame while we drive over at RIT’s test track. They have also wired up a push button on the steering wheel to allow the driver to trigger when to record data. That way, we will be able to take data on how our vehicle handles specific obstacles on the track.

Finally, Ethan’s group has completed even more strain gauge testing on the MTS machine. We have taken stress and strain data for several tie rods from last year’s vehicle as well as our shocks. This data has been used to improve our mechanism model as well as several pieces of our analysis. We’re hoping Ethan’s work will lead to even better scores at our design report since we’ll be able to validate our models with more data than ever before.

TESTING, ITERATING, AND IMPROVING

By: Loren McDonald (Mechanical Engineering, ’20)


One of our biggest goals for this year is to improve how our team tests, iterates, and improves our designs after we complete the car. One of the main reasons that we set our deadline so early in February is that we want to ensure that we have sufficient time to thoroughly test our car before we arrive at competition. Our whole philosophy is that if something breaks on our test track, we have the ability to understand why the part failed, to figure out how to prevent that failure from occuring again, and to design an entirely new part.

One of the integral pieces of the puzzle that makes this iteration possible is the new HAAS machine that the Mechanical Engineering Department just purchased. Noah is planning to design and build several different uprights over the course of testing. The suspension geometry is very complicated, and we’ve had issues in the past where things don’t line up exactly the way we thought they were going to. This year, if we run into that issue, we’ll be able to design and quickly manufacture an entirely new upright to correct the problem. Once we are satisfied with the upright design, we’ll send our design to DK Manufacturing to have it professionally built to extremely high tolerance.

Another example of the iteration process, is Marial’s Usability team and the brake rotors. With help from Paragon, we can easily manufacture several different rotor designs. She has already had a few different designs made, but after testing, we will be able to quickly manufacture more optimized designs should we need to.

While I’ve only given a few examples, our entire team has understood the need to iterate, and we’ve adopted it into our design practice and timelines. Thanks to some insight from our adviser, Professor Muir, our team is really pushing to test more than we have in previous years. Also, thanks to a huge donation from Jerry Toporek, we have been able to acquire several instruments for data acquisition that we hope to utilize in the next couple months.

NOVEMBER SUSPENSION UPDATE

By: Loren McDonald (Mechanical Engineering, ’20)


Noah Meyers and the suspension team have been busy this season. Our team has been trying to incorporate aluminum components into our suspension system for years, and we believe that this year we will be successful with designing a suspension system that utilizes aluminum components in place of the heavy, steel components used in previous years. Noah’s group has been working hard in NX to validate our designs, and thanks to some great work from Jaafar, we believe that the aluminum components will be structurally sound. Noah will be giving his design review in about a month, so come check back in to see how much aluminum we manage to incorporate in our design this year.

Besides using aluminum, we are trying to critically damp this year’s suspension system. Noah’s team has been working with Chris Pratt, the Mechanical Engineering Department’s lab technician, to design an experiment to test our suspension system on the MTS machine. With this data we should be able to critically damp the suspension system, so that our vehicle will be able to cross obstacles better than ever.

Another project that we have been working on is the mechanism model of this year’s car, seen in the picture. Marcos has been working with all the PTLs to build an accurate simulation of our car. With this model, we will be able to analyze how our car will perform over a variety of obstacles, and it should lead us to more informed engineering decisions. Finally, it will be very beneficial when we go to present our suspension subsystem at this year’s competitions.

Another big advancement to the suspension subsystem this year is that we are going to be designing custom rear hubs. During last year’s design presentations, one consistent piece of feedback that we received was that we needed to be designing our own hubs. So this year, we decided to act on our feedback and work to design our own custom, rear hubs. Not only will this score us more points during our design presentation, but it will also help us remove even more weight from the suspension system.

NOVEMBER USABILITY UPDATE

By: Loren McDonald (Mechanical Engineering, ’20)


Usability has quickly become one of the most popular subsystems on the Baja Team. After driver training and Midnight Mayhem, several of our new members already had ideas for improving the car, and the most common opinion was that we needed to improve the steering and driver interface.

Several new members have already started honing their FEA skills by working on analyzing our new brake rotor designs. Since many of the usability components make great first-year projects, Marial has been keeping our new members busy. After practicing doing analysis, our new members helped Marial create a handful of different brake rotor designs. As the picture shows, we’ve already cut a few prototypes out of wood, and we are going to be making a few metal brake rotors in the near future.

Thanks to our awesome waterjet and laserjet sponsor, Paragon Steel Rule Dies, we are going to be able to quickly manufacture several of our new designs, including those done by our new members! Throughout the season, we hope to keep using the help of our sponsors, like Paragon, to be able to design, test, and iterate upon more designs than ever before.

Finally, some of our new members have already started working on this year’s pedal design. One new member in particular, Scott Smith, has already completed his first iteration of the gas pedal. Sometime soon we will be 3D printing his design to see how it feels in real life as opposed to on the computer screen. While we are still iterating on our usability subsystem designs, one thing is for sure, we are going to have a very comfortable interface for the driver this season.
