摘　　要：为了确保电池包在使用过程中的安全性和可靠性,基于有限元理论,结合电池包三维几何参数,合理划分网格,设置边界条件,优化构建了电池包模型。基于电池包模型对电池包静强度进行了仿真计算,计算求解了在刹车、加速、左右转弯和爬坡5种典型工况下,电池包的静强度变形云图和应力变化云图,获得了不同工况下电池包所承受的最大等效应力和屈服强度,验证了电池包结构的可行性与安全性,提出了加强电池包箱体盖板刚度的优化建议,为进一步优化电池包结构设计提供了的理论指导和技术支持。To ensure the safety and reliability of the battery pack in the process of use,this paper uses the finite element theory and three-dimensional geometric parameters of the battery pack to reasonably divide the grid,set the boundary conditions,and optimize the battery pack model.Based on the battery pack model,the static strength of the battery pack is simulated and calculated.We calculate and solve the static strength deformation cloud diagram and stress change cloud diagram of the battery pack under five typical working conditions of braking,acceleration,left and right turning and climbing.The maximum equivalent stress and yield strength of the battery pack under different working conditions are obtained,and the feasibility and safety of the battery pack structure are verified.The optimization suggestions for strengthening the rigidity of the cover plate of the battery pack box are put forward.The research conclusions have certain theoretical guidance and technical support for further optimizing the structure design of the battery pack.
