| Abstract: |
| 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. |
