Stress Analysis on Hinge Sleeve and Cylinder of China-Type Cubic-Anvil High Pressure Apparatus under High Pressure
-
摘要: 运用有限元理论，基于ANSYS对国产六面顶压机的铰链梁、工作缸和销轴进行了接触分析。模型中首次引入销轴，约束销轴的运动，使凸耳处的载荷情况更接近实际工况，避免了对铰链梁和工作缸单独分析所进行的大量近似和简化。模拟结果表明：铰链梁上的von Mises应力峰值主要分布在凸耳内通孔处，最大应力值为348.32 MPa；工作缸上的von Mises应力峰值主要分布在工作缸底部圆弧处，最大应力值为242.87 MPa；应力峰值均低于许用应力（486.67 MPa）。模拟结果得到了大量高压实验的验证。Abstract: 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.
