Abstract: As the core power source of the electric formula racing car, the importance of the battery is self- evident. In order to ensure the stable operation of the battery under various road conditions and working conditions, the design scheme of the battery box is particularly important. The scheme not only considers the strength factor, but also cannot ignore its lightweight, reliability and other properties. In view of the above discussion, CATIA software is used to design and assemble the main parts of the power battery box of the formula racing car. Under the premise of ensuring the structural integrity, the finite element simulation analysis is carried out by ANSYS software. The specific operation steps include determining the material properties, correctly meshing the model and determining the load and constraint application. Combined with ANSYS finite element simulation software, the static stress analysis of the three-dimensional model of the battery box is carried out. The stress and deformation cloud diagram of the model is obtained through the simulation results, and the position where the battery box is most prone to deformation in the subsequent work process is determined, which provides valuable guidance for the subsequent structural optimization design.
