Stress Analysis on Hinge Sleeve and Cylinder of China-Type Cubic-Anvil High Pressure Apparatus under High Pressure

The contact analysis of hinge sleeve, cylinder and dowel in China-type cubic-anvil high pressure apparatus were conducted by finite element method and ANSYS. To avoid excessive similarity and supposition for ear and obtain exact simulation results, the fixing dowel, whose movement is constrained, was introduced in the model. The results indicated that the peak values of von Mises stress in hinge sleeve and cylinder are located within the inner ear and the bottom of cylinder, respectively, and the corresponding calculated maximum von Mises stresses are 348.32 MPa and 242.87 MPa, respectively, which are lower than allowable stress of 486.67 MPa. These results have been verified by numerous experiments.
