摘要

本文基于ANSYS Workbench平台对电池包箱体进行静、动态有限元分析,找到箱体结构的薄弱位置。 采用Optistruct软件,运用形貌优化和复合材料优化技术对箱体进行优化设计,得到了在箱体上盖设置的凸包结构的最优几何参数和平面布局,并构建了优化后上盖的三维模型,同时得到下箱体各层组的厚度分布情况及最优厚度。经验证,优化后箱体最大变形量较优化前降低了82%,刚度提升显著,最大等效应力降低了70%,箱体强度得到明显改善,其一阶固有频率为32.5Hz,可避免共振情况发生,优化后箱体重量减轻了67%。优化后电池包箱体对动力电池安全工作能起到更有效的防护作用,且轻量化效果显著,此研究为进一步分析实际电池包箱体结构奠定基础。

Abstract:

In this paper ANSYS Workbench platform is used for static and dynamic finite element analysis of the battery pack enclosure, and the weak position of the box structure is obtained. The box is Optimized by the topography and composite material optimization, The optimum geometric parameters and plane layout of the convex hull on the box cover are obtained by topography of the Optistruct software, final the three-dimensional model of the optimized upper cover is established. The thickness distribution and optimal thickness of each layer in the lower box is obtained by the composite material optimization. After verification, the maximum deformation of the box after optimization is 82% lower than that before optimization, the stiffness is significantly increased, the maximum equivalent stress is reduced by 70%, and the box strength is significantly improved. The first-order natural frequency is 32.5Hz, which can avoid resonance, the box weight is reduced by 67. After optimization the battery pack box can play more effective protective role for the safe operation of the power battery, and the weight reduction effect is significant, the research lays the foundation for further analysis of the actual battery box structure.
