Study In Strength And Stress Monitoring Of Valve-body Of Turbine Servo

The unsteady temperature field, Mechanical stress field, thermal stress field and the combined stress field of valve-body of 125WM Turbine Servo during cold, warm and hot on-off period are calculated by 3D FEM in this paper using FEM software. Also, based on the FEM calculation, the distribution patterns of temperature field, Mechanical stress field, thermal stress field and the combined stress field and their changing law with time are obtained through FEM analysis. Based on FEM calculation and analysis, math models of stress and life monitoring are established, the application for stress and life monitoring is programmed with Visual Basic6.O.Ding Zhushun ( Mechanic Design & Theory)Directed by Prof.Peng Zhenzhong& Prof.Wang Zhangqi...
