This design takes the suspension system of FSC race car designed by the race team ,which is from Beijing institute of technology, Zhuhai, as the research objective. The the design mainly work in several aspects. This design was based on the competition rules of FSC. The calculation of the wheel track and spread of axles as well as the design of some related components including the front and rear suspension column have been conducted after a clear idea of the design had been made. The next step is the analysis of wheel alignment parameters in order to make out whether it affects the performance of the car. When unequal-length wishbone suspension is selected, the paper chose the type of flexible components, absorder, guide mechanism and other part...
