【摘要】 为满足工艺流程的需求,压力容器需要开孔接管,这使得开孔接管区的应力状态异常复杂,会导致压力容器出现高应力区。本文运用ANSYS Workbench软件对压力容器筒体上正交接管和斜向接管的应力状态进行了分析比较。结果表明:简体上斜向开孔接管的最大应力强度比正交相同内径的开孔接管的要小。更多还原

【Abstract】 Due to the technology process requirements,pressure vessel was always in need of opening apertures and installing tubes,which would result in highly complex stress state at the opening tubing connection,and became one of the high stress area on pressure vessel.The stress on the opening tubing connection between orthogonal tube and slant tube was analyzed and compared by utilizing ANSYS/Workbench software.Results indicated that the maximum stress intensity of the slant opening tubing connection was smaller than that of orthogonal opening tubing connection.更多还原
