Date: Spring 2011

Requirements:
The primary requirement for our project was to build and race the FSAE 2010 and 2011 models in Adams/Car to determine which one performs better. The second requirement was to test different tires and suspension setups. Tires and suspensions are very important to the car, because they directly affect the performance of the vehicle. The main constraint was that Adams/Car cannot simulate driver's variability. Also, Adams/Car is not user friendly software, and certain model's conditions are hard to control. For example, in a drag race, the driver increases the RPM (launch) before the starting time, but we could not simulate this launch in Adams/Car.

Problem:
The purpose of our project was to create an Adams/Car model to assess the functionality and feasibility of the program, and optimize and compare the performance of the 2011 car. The project arose out of the need for preconstruction dynamic testing of the vehicle.

Solution:
The team designed, built, and simulated models in Adams/Car. All design and dimension parameters were obtained from the Formula SAE database in order to make the Adams/Car model as realistic as possible. The team delivered working Adams/Car models for both the 2011 and 2010. The team also provided quantitative results for suspension setup for 2011 car to be used at the September competition. The team also delivered results from the simulated race between the 2011 and 2010 Formula SAE cars in Adams/Car.
