Abstract: According to the rules of FSEC racing and the demand of power system, this paper designs a kind of battery box for FSEC racing car. The finite element model of the battery box is established in CATIA. Through the analysis of the working conditions of rapid acceleration, rapid deceleration, turning and durability by using the ANSYS workbench finite element simulation software, the deformation cloud diagram, stress cloud diagram and fatigue alternating stress cloud diagram of the battery box are obtained, and the maximum stress value and the maximum deformation position are defined, which provides the direction for the follow-up structural optimization design. The research and development of simulation driver by using ANSYS software greatly improves the design efficiency and promotes the development of the competition.
