RIT FSAE Vehicle Dynamics System - P07221

The Vehicle Dynamics Senior Design Project stemmed from the desire of the RIT Formula SAE Racing Team to improve

the design and performance of their open-wheel styled vehicle. This project expands upon the Data Acquisition Senior

Design Team’s work by utilizing vehicle test data to provide a correlated vehicle model using CarSim software. This

computer program will be used by the Formula SAE Racing Team to simulate tuning and vehicle design changes;

expediting design evolution. Additional features provided by this project are a more organized method of testing, a

system of data analysis, a test stand for organization of test day equipment, and a vehicle dynamics database to

organize vehicle data and analysis tools.
