| 中文摘要: |
| 运用非线性有限元方法对汽车门框密封条压缩进行仿真分析，对3种仿真模型与试验汽车门框密封条的断面压缩变形和压缩力进行对比。结果表明：汽车门框密封条的压缩力主要由泡管的变形产生，钳口卡爪变形对压缩力有一定的影响，但影响较小；泡管内外表面包覆层密实胶与内部海绵胶性能的差异对压缩力有较大影响，建模时应加以考虑，以提高仿真分析精度。 |
| 英文摘要: |
| The nonlinear finite element method was used to simulate the compression of automobile doorframe sealing strip.The compression deformation and compression force of three simulation model and test automobile doorframe sealing strips were compared.The results showed that，the compression force of the automobile doorframe sealing strip was mainly caused by the deformation of the bubble tube，and the deformation of the jaw had a certain influence on the compression force，but the influence was small.The difference between the performance of the inner and outer surface coating layer dense compound and the internal sponge compound of the bubble tube had a great influence on the compression force，which should be considered in the modeling to improve the simulation accuracy. |
