Abstract: In recent years, college students continue to develop motor sports. In order to improve the stability of BSC car racing and meet the requirements of structural lightweight, the design goals and design flow of steering system are established according to the racing rules. Hard point coordinates of 3D model in UG are used with Adams / Car module to establish simplified kinetic model. The influence of each system parameter on racing steering is analyzed. The performance parameters of steering system are designed and calculated. The structure of steering system is simplified by ANSYS statistical analysis. Lastly, the optimized results are used in BSC racing design. This paper presents a good reference for the same type of front suspension steering system design, shortens the design cycle, and promotes Baja event development.
