| Abstract: |
| The effect of initial compression ratio，pressure，rubber material hardness，friction coefficient and shaft speed on the deformation，contact stress and equivalent stress of the rectangle rubber seal was analyzed by using Abaqus finite element analysis software，and the structure of rectangle seal was optimized.The results showed that the higher the initial compression ratio was，the better the sealing effect of seal was.The properties of materials and the friction coefficient were the important factors affecting the sealing performance.The rectangle seal was unsuitable for dynamic sealing.When chamfer angle was set on the side of rectangle seal which contacted with the sidewall of sealing slot，the sealing performance could be effectively improved. |
