| Abstract: | The formula of interference capacity of mechanical seal was deduced based on the principle of torque equilibration.The finite element model of interference fit of mechanical seal ring was established,the stress distribution within the nodes of the seal ring was calculated by ANSYS software,and was compared with the result calculated by traditional thick-walled cylinder theory.The result indicates that finite element analysis method can calculate the stress distribution of interference fit parts more accurat... |
