| 采用两参数Mooney-Rivlin超弹性本构模型，对比不同硬度高速列车塞拉门橡胶密封条的压缩载荷-压缩量的仿真结果与试验结果，确定不同硬度密封条的材料常数；对优化后密封条的压缩特性进行了仿真分析和对气密性进行了试验验证。结果表明：在4 mm压缩量下，优化前后的密封条与门框压条间的最大接触压力基本相同；与优化前密封条相比，优化后密封条的压缩载荷减小了29.4%，密封性能提高了近1倍。 |

| Abstract：Using the two parameter Mooney-Rivlin hyperelastic constitutive model，the simulation and
test results of the compression load-compression amount of the rubber sealing strips for the sliding plug door
of high-speed train with different hardness were compared，and the material constants of the sealing strips
with different hardness were determined. The compression characteristics of the optimized sealing strip were
simulated and the air tightness was verified by experiments. The results showed that under the compression
amount of 4 mm，the maximum contact pressure between the door frame bead and the sealing strip before and
after optimization was basically the same. Compared with the unoptimized sealing strip，the compression load
of the optimized sealing strip was reduced by 29. 4%，and its sealing performance was nearly doubled |
