摘　　要：采用ANSYS有限元分析方法,通过改变操作压力、接管外半径、筒体壁厚、接管壁厚、接管形式五个参数,来考察其对圆柱壳开孔接管区应力分布及其最大应力的影响。结果表明:随着操作压力、接管外半径的增大,圆柱壳开孔接管区最大应力随之增大;随着筒体壁厚、接管壁厚的增大,圆柱壳开孔接管区最大应力将随之减小。在相同的参数情况下,平齐式接管的最大应力比内伸式接管的大。This experiment uses ANSYS finite element analysis method to examine the influence of stress distribution and maximum stress of cylindrical shell nozzle zone by changing parameters of design pressure, namely cylinder radius, nozzle radius and cylinder thickness, nozzle thickness and nozzle type. The result shows that with the increase of design pressure and nozzle radius, maximum stress increases. With the increase of cylinder thickness, nozzle thickness increases, and the maximum stress decreases. In the case of same parameters, maximum stress of flat nozzle is larger than inner extension pipe.
