Abstract: In this paper some brand electric car battery shell hydroforming process simulation analysis, first of all, through the experimental platform to build hydraulic forming hydroforming experiments, secondly, based on nonlinear finite element software DYNAFORM hydraulic simulation, prove the correctness of the finite model and simulation method, since then on the basis of some brand electric car battery shell finite element modeling, analysis of the conditions of different pressure circle edge pressure, hydraulic pressure battery shell wall thickness, the influence of hydraulic deep drawing forming technology for battery shell to offer reference to the practical application.

Key words: Typical plate sample, Dynaform, Battery shell, Hydraulic deep drawing

摘要： 文章针对电动汽车的电池壳充液拉深工艺进行仿真分析,首先通过自行搭建的液压成形实验平台进行板材充液成形实验,其次基于非线性有限元软件Dynaform进行液压仿真,证明有限模型及仿真方法的正确性,最后在有限元仿真方法正确性的基础上对电动汽车的电池壳进行有限元建模与仿真分析,讨论不同压边圈压力和液压压力对电池壳壁厚的影响,给电池壳充液拉深工艺的实际应用提供参考。
