摘要

随着国家对节能减排和环境保护的日益重视，电动汽车已成为汽车技术发展的热点。动力电池决定着电动汽车的综合性能，而电池盒的防护性能直接影响着车辆的安全。因此，以电池箱为研究对象，根据动力电池进行箱体设计。箱体布置在汽车底盘下方，基于SolidWorks和ANSYS Workbench软件建立箱体的三维模型和有限元模型。在典型工况下对箱体进行了静力、冲击和模态分析。基于下箱刚度，对下箱进行了优化，并进行了模态分析验证。分析结果表明，通过在箱体底部增加X型加强筋，可以提高箱体的刚度，设计的动力电池箱体能够满足汽车的实际安全要求。

Design and Optimization of Electric Vehicle Power Battery Box

As the country pays more and more attention to energy saving, emission reduction and environmental protection, electric vehicles have become a hot spot in the development of automobile technology. Power battery determines the comprehensive performance of electric vehicle, and the protective performance of battery box directly affects the safety of the vehicle. Therefore, the battery box is taken as the research object, and the box is designed according to the power battery. The box body is arranged under the chassis of the car, and the 3D model and finite element model of the box body are established based on SolidWorks and ANSYS Workbench software. The static performance, impact and modal analysis of the box body are carried out under typical working conditions. Based on the stiffness of the lower box, the box is optimized and verified by modal analysis. The analysis results show that the stiffness of the box can be increased by adding X type stiffeners at the bottom of the box, and the designed power battery box can meet the actual safety requirements of the car.
