Abstract: In order to understand and master the distribution of strain and stress of the electric vehicle battery-switchable chassis under the rated load, the type of the battery-switchable chassis is studied, the composition structure of the cell split type of battery-switchable chassis is analyzed, the three-dimensional model of the chassis is drawn by SolidWorks software, and the structure analysis of the type of battery-switchable chassis is carried out by using ANSYS. The equivalent stress cloud diagram and total deformation cloud diagram are obtained. Based on this, the structure optimization is carried out, and the verification and analysis are carried out to provide the optimization basis for the overall research and development of the battery-switchable chassis, so as to promote the rapid development of the electric vehicle battery-switchable industry.
