Vehicle dynamics has evolved into an increasingly indispensible discipline to supplement the design of automobiles, especially racecars. Every single component of the car and the environment with which it interacts contributes to the overall dynamic behavior of the vehicle. For Formula Society of Automotive Engineers (FSAE) cars in particular, these parameters become extremely critical and hence require robust and accurate physical testing methods, which are expensive and time consuming, warranting the need for virtual testing methods. The Bearcat Motorsports team (BCMS) lacked this capability of predicting vehicle dynamic behavior, relying on previously available test data and the performance of the car after fabrication. Hence, a thorough multi-body dynamics model has been developed to overcome this inadequacy. The 2013 race car is used for this study and ADAMS/Car is used as a multi-body development platform. ADAMS/Car multi-body model consists of different automotive subassemblies modeled as independent subsystems, which can interact amongst themselves to mimic the overall dynamics of a physical car model. Each subsystem requires data pertaining to its characteristics such as mass, inertia, center of gravity, which can be tuned to calibrate and eventually validate the model against data obtained from physical testing. This makes it imperative to bring together the work done by all sub-system teams over the course of the year. For simulation of road-tire interface, the PAC2002 tire model [2] is used, which is the latest Pacejka Tire Model. A new ADAMS template is made for the anti-roll bars and the strut structure. The model can predict full vehicle dynamic behavior apart from generating sub-system specific vehicle dynamic parameters. The validation of a full vehicle model is a multi-year project and is not within the scope of this thesis. However, the initial dynamic model is now able to help the team predict vehicle dynamic trends and evolve their designs based on previous design ideologies. The future work for this project will include further calibration and validation of the model and then running the simulation model on a complete virtual endurance track.
