| 中文摘要: |
| 建立快开阀芯橡胶密封垫密封结构的Mooney-Rivlin 非线性有限元分析模型，分析橡胶密封垫在装配状态下的等效Von Mise 应力分布及等效Von Mise 应力与橡胶密封垫轴向压缩量的关系，研究橡胶密封垫在工作状态下的密封性能。橡胶密封垫装配时，轴向压缩量增大，应力较大的区域位置未发生变化，基本在上、下接触面；轴向压缩量增大，Von Mise 应力增大；最大Von Mise 应力与轴向压缩量呈非线性关系。设计合理的轴向压缩量对于保证橡胶密封垫的密封性能和使用寿命非常重要。本设计橡胶密封垫的合理轴向压缩量为0.8 mm，密封垫轴向压缩量和轴向预紧力的模拟结果与试验结果比较吻合。 |

| In this study，the Mooney-Rivlin nonlinear finite element model of the sealing structure of faucet cartridge rubber gasket was established.The distribution of equivalent Von Mise stress and relationship between equivalent Von Mise stress and axial compression ratio of the gasket were analyzed in the assembled state，in order to evaluate the sealing performance of the gasket.During the assembling，when the axial compression ratio increased，the Von Mise stress increased but the high stress location didn’t change，which were substantially at the up and bottom contact surface.The maximum Von Mise stress showed nonlinear dependence on the axial compression ratio.It was found that the design of axial compression ratio was very important to ensure the sealing performance as well as the service life of rubber gasket.The optimized axial compression amount in this study was 0.8 mm，and it was demonstrated that the simulated results of the axial stress agreed well with the experimental test results. |
