| Abstract: |
| The axisymmetric model of rubber O-sealing ring was established. By using nonlinear finite element method, the contact stress distribution under different initial compression ratios and medium pressure was researched. The relations between contact widths and initial compression ratios were analyzed. Through data processing, the disciplines of maximum contact pressure along with pressure and initial compression ratios were obtained, which can provide references for the structural design of this type O-sealing ring． |
