| 中文摘要: |
| 基于非线性有限元接触理论，建立橡胶O形密封圈组合的有限元模型，分析了初始压缩率、介质压力、橡胶硬度、往复运动速率及摩擦因数对O形密封圈密封性能的影响。结果表明：压缩率对O形密封圈组合的密封性能影响较小，橡胶硬度和摩擦因数是O形密封圈组合密封性能的重要影响因素，合理选择各O形密封圈材料硬度可以提高O形密封圈组合整体的使用效率。 |

| Based on the theory of nonlinear finite element contact， the finite element model of rubber O-ring combination was established.The effects of the initial compression ratio，media pressure，hardness of rubber material，reciprocating movement speed and friction coefficient on the sealing performance of O-ring were analyzed.The results showed that the influence of initial compression ratio on the sealing performance of O-ring was small，while the hardness of rubber material and friction coefficient were the important factors.Therefore，proper selection and combination of rubber materials with different hardness could improve the sealing performance. |
