Performance Analysis of O-ring Angle Seal for Ship Underwater Device
In order to study the changes in stress state and sealing performance of O-ring seals used in underwater devices with changes in external pressure,a finite element model of the sealing groove and O-ring in the triangular sealing area was estab-lished.The super-elastic rubber elements were used to simulate the changed Von Mises stress,contact pressure and other param-eters of the O-ring under different pressures,and the sealing effect of the diagonal seal was experimentally verified.The results showed that as the external pressure increases,the contact pressure between the O-ring and the sealing groove also increases syn-chronously,as well as the sealing pressure that can be overcome.Without damaging the O-ring and sealing groove,it can meet the sealing requirements.
