Effects of Suspension Geometry and Stiffness Asymmetries on Wheel Loads During Steady Cornering for a Winston Cup Car

Tuning a race car for good handling requires accurate prediction of the tire normal loads and tire orientation as specified by steer and camber angles. This paper describes the development and examples of the application of computer models which have been developed to predict suspension geometry characteristics and wheel loads for Winston Cup cars running on banked tracks. Example cases are presented illustrating the effects of roll center movement front spring split different rates right to left), and cross weight percentage (wedge).
