A seven degree of freedom non-linear multi-body dynamics model was built as a tool to help design and analyze the effects and requirements of an active suspension system on a Formula Student Racecar. The model offers several improvements over a ‘typical’ linear model by accepting nonlinear damping characteristics (as are commonly found in racing applications by design), suspension travel limits, and most notably ‘ballistic’ effects where the wheel loses contact with the ground. Developed using a combination of MATLAB and Simulink, the model is both functional and flexible.
