摘　　要：在新车设计阶段,一款全铝框架纯电动汽车的无边框铝合金车门在加载额定外力的条件下,存在明显下沉的问题,通过运用有限元软件分析并查找下沉的原因。然后,对车门下沉的原因进行仿真验证,并提出5种优化方案。把五种优化方案的分析结果进行对比,选取最优的一种可行性方案运用到实际设计过程中。以上分析流程和优化方案可以为后续铝合金车门下沉问题的研究提供参考。In a new car design phase, the no-frame aluminum alloy door of a pure electric vehicle with a full aluminum frame has an obvious sinking problem under the condition of loading external force. This paper analyzes and finds the sinking reason of the car door by using the finite element analysis software. Then, the sinking reason of the car door is simulated and verified, and five optimization schemes are put forward. To compare analysis results of above five optimization schemes, it chooses the best feasible scheme to apply to the design process. The above analysis process and optimization plan can provide reference for fur- ther study of the car door.
