Department of Automotive Engineering, Tsinghua University of Physics ,Tsinghua University Abstract: Tsinghua University FSAE program currently has no rigorous method for designing and analyzing the student-made racecars. Th is paper is plete the suspension and to leave them not only a design but an idea of how to design. In suspension design process, I referred the general process. For the first, bined regulatory requirements and determined the free frequency of the car. And then, I calculated a number of parameters, laying the foundation for the further calculation . For the next, I made it out how wheel alignment parameters will influence the performance of the car, and figured out some basic principles. pleted the parameter model of the fro nt suspension with ADAMS. After that, I started to simulations. But results were not so satisfied. By using ADAMS Insight. ,I got a set of ideal results with which the changes of wheel alignment paramete rs was within the range of e
