【Abstract】 Based on the combined method of finite element analysis and the empirical formula,this analysis paper calculated the valve vibration modal and valve stress and deformation due to the combination of design loads and SSE seismic loads. Then according to the ASM E code,the evaluation of stress and strength check of pressure boundary components was made.更多还原
