%X 设计两种截面结构（方案1为非对称结构，方案2为对称结构）的新能源汽车动力电池包壳体用橡胶密封件，利用有限元仿真分析橡胶密封件的力学性能，并与实测结果进行对比；通过防水试验验证橡胶密封件的密封效果。结果表明：与方案2橡胶密封件相比，方案1橡胶密封件的刚度更小，有限元仿真结果与实测结果相差很小，有限元仿真能够较好地分析和预测橡胶密封件的力学性能；两种方案橡胶密封件的最大应变非常接近，但方案1橡胶密封件的最大应变在底部，方案2橡胶密封件的最大应变在直条密封筋与环形密封筋交接处，且上下面的接触应力相同，方案2橡胶密封件的截面结构有利于提升密封性能，并保持长久的密封效果；两种方案橡胶密封件均具有良好的实际密封效果。;Two kinds of rubber seals were designed for the new energy vehicle power battery pack shell with two sections structure（scheme 1 was asymmetric structure，scheme 2 was symmetric structure）.The mechanical properties of the rubber seals were simulated and analyzed by the finite element method，and compared with that by the the measuring.The sealing effect of the rubber seals was verified by the waterproof test.The results showed that，compared with the scheme 2 rubber seal，the stiffness of the scheme 1 rubber seal was smaller，the difference between the finite element simulating results and the measuring results was very small，and the finite element simulation could analyze and predict the mechanical properties of the rubber seal better.The maximum strain of two scheme rubber seals was very close，but the maximum strain of the scheme 1 rubber seal was at the bottom，and the maximum strain of the scheme 2 rubber seal was at the joint of straight sealing bar and ring sealing bar.Section structure of the scheme 2 rubber seal with same contact stress above and below was beneficial to improve the sealing performance and maintain the long-term sealing effect.Two schemes rubber seals had good sealing effect
