| 目的 解决真空法兰密封中的金属密封圈寿命难以预测的问题。方法 基于金属密封圈的失效机理，提出一种疲劳仿真方法，对金属密封圈的使用寿命进行有效预测。通过有限元仿真方法对金属密封圈安装过程及其使用过程进行仿真模拟，得到金属密封圈使用过程的应力分布，然后结合Conffin-Manson疲劳模型，对金属密封圈的使用寿命进行疲劳仿真，最后设计加速寿命试验，对其仿真结果进行验证。结果 疲劳仿真所得的金属密封圈使用疲劳寿命为26 915次温度循环，加速寿命试验结果为28 401次温度循环，仿真误差为5.23%。结论 构建的安装过程和疲劳仿真模型与实际相符。 |

| Aiming to solve the problem that the life of metal sealing ring is difficult to predict, this paper proposed a fatigue simulation method to predict the service life of metal sealing ring effectively based on the failure mechanism of metal sealing ring. The metal sealing ring installation process and its service process were simulated by the finite element simulation method to obtain the stress distribution of the metal sealing ring in the service process, and then a fatigue simulation on the service life of the metal sealing ring was conducted based on the Conffin-Manson fatigue model. Lastly, the simulation result was verified by an accelerated life experiment. The simulation results show that the service life of the metal sealing ring obtained from the fatigue simulation is 26,915 temperature cycles, and the accelerated life experimental results is 28,401 temperature cycles, and the simulation error is only 5.23%. Therefore, it can be concluded that the constructed installation process and fatigue simulation models are consistent with the actual situation. |
