Design And Analysis Of One-Piece 10” Carbon Fiber Wheels For Zips Racing Zr20 Formula Sae Racecar, Patrick Kruse, Henry J. Wathen, Jordan J. Hyde, Nicholas D. Dobben, Jordan D. Blake

Williams Honors College, Honors Research Projects

Reducing the weight of a vehicle in racing can substantially improve the vehicle dynamics and general performance capabilities. More specifically, the reduction of the unsprung corner weight can provide noticeable performance gains in handling and responsiveness, leading to a quicker, more agile car due to a lower yawing moment of inertia. Unsprung weight reduction also improves the car’s ability to maintain contact between the tires and the road surface for a more consistent grip. In this project we identified the loads that act on the wheel rims according to the data collected from the sensors in the car’s suspension, and …

Formula Sae Monocoque Chassis Development, Kc Egger, Brian Ford, Kyle Nagao, Neal Sharma, Donovan Zusalim

Mechanical Engineering

Formula SAE is a collegiate competition hosted by SAE International with the primary goal being to design, manufacture, and race an open wheel race car. The Cal Poly Racing Formula SAE team strives for improvement every race season and has remained competitive as a result. The 2019-2020 management team determined that further research and development towards the chassis would yield the greatest performance benefit for future seasons, as the previous chassis platform limited packaging and mounting options for vehicle subsystems which interfaced with the chassis.

Zips Electric Racing Suspension Design, Christopher Thompson, Madison Hughes, Erikah Jackson, Anna Signorino

Williams Honors College, Honors Research Projects

As a member of the 2020 Zips Electric Racing Design Team, I will design the suspension subsystem with three other members. Specifically concentrating on the steering and suspension mounting points, we will optimize and improve some components from the previous year's design. Modeling of components will be done in Solidworks and suspension vehicle behavior will be modeled in MATLAB and Optimum Kinematics.

Torsional Stiffness Of A Race Car, Reiley A. Schraeger, Cameron Kao, Raymond Deng, Omar Roman

Mechanical Engineering

Torsional stiffness plays a major role in any road vehicle. To understand torsional stiffness of a vehicle and make future iterations and improvements, a proper torsional stiffness jig is required to prove accurate and useful data. This report encompasses the new and improved testing jig and potential improvement ideas for more accurate results. With real data result relating to FEA calculations, designers can be confident in the FEA changes to torsional stiffness is accurate and will yield the probably results they desired. This report shows the methodology, manufacturing process and testing procedure to use on any Baja or SAE vehicle …

Sae Baja Custom Caliper And Upright Design, Katelynn R. Kise

Williams Honors College, Honors Research Projects

The Zips Baja Off-Road Racing team had a successful 2018 season however some aspects of the car needed to be updated and improved for the 2019 season. This reports captures the design cycle performed to improve the cost, integration, and reliability of the front braking caliper and upright.

2015 Zips Sae Baja Brakes And Throttle System, Philip A. Bennett

Williams Honors College, Honors Research Projects

The SAE Baja student design team at The University of Akron is one of the longest-standing design teams at the university. The purpose of this team is to design, manufacture, test, and race an off-road vehicle within the guidelines of competition established by the Society of Automotive Engineers. The vehicle is made up of a small number of subsystems including frame, drivetrain, suspension, steering, and braking. The following will discuss all aspects of the design process of the braking and throttle system of the 2015 Zips Baja car. This process includes several steps and considerations such as design goals, system …

The University Of Akron 2015 Sae Zips Baja Off-Road Racing Team 2015 Suspension System Design, Ryan W. Timura

Williams Honors College, Honors Research Projects

Baja SAE has been an important part of the University of Akron for the last 20 years. In the early stages, Zips Baja won many races and was one of the best Baja teams around. In more recent years, the teams have not been able to keep up the high place finishes. The 2015 Baja team aims to start a new trend of high place finishes for the years to come. With many design leaders returning from the previous year, passed down knowledge, and experience from last year, it should be an attainable goal.

Formula Sae Turbocharger Engine Development, Eric Griess, Kevin Mccutcheon, Matthew Roberts, William Chan

Mechanical Engineering

This project, Formula SAE Turbocharger System Development, was sponsored by the Cal Poly, San Luis Obispo Formula SAE team. The team proposed this project in order to have a powerful yet lightweight engine so they can be extremely competitive at their competition. The baseline output of the single cylinder 450cc engine (2006 Yamaha WR450F) was 46 horsepower and 27 ft-lb of torque. The goal of this project was to increase the output of that engine to 60 horsepower and 35 ft-lb through the use of a turbocharger.

Sae Baja: Final Drive Gearbox, Michael Mccausland, Michael Watkins, Ian Masterson, Andrew Sommer

Mechanical Engineering

This paper presents the results of a manual transmission project for SAE Baja. A full engineering process is documented, including problem definition, scheduling, conceptualization, decision theory, synthesis, analysis, manufacturing, and testing. A comparison is made between existing and potential mechanical power train solutions. The final design is analyzed in dynamic simulations, AGMA stress, predicted FFT spectrums, and shifting rod buckling. A number of complicated parts are manufactured through investment casting and direct CNC machining. Issues in the final assembly have prevented the project from being fully realized, recommendations are made for future SAE Baja teams.
