| Abstract: |
| The hyperelasticity theory and heat transfer principle were applied to the coupled field simulation of thermal and structure of O-ring with block ring by finite element analysis.The effect of working parameters on seal performance was studied.The results showed that the largest deformation appeared at bottom part and contact position with cylinder wall，the biggest Mises stress occurred at bottom part.The shear stress and maximum contact pressure increased significantly with the increase of medium pressure.The frictional and mechanical hysteresis led to high temperature field in seal ring.The temperature rise of seal ring evidently increased when medium pressure，relative slide speed and medium temperature increased.The parametric simulation system of seal ring was then developed based on ANSYS/MATLAB which was efficient and effective for the analysis of different type and dimension of O-ring seals under various working conditions. |
