摘　　要：压力容器由于工艺和结构上的要求,常常需要设置各种大开孔结构,超出了等面积法的适用范围。采用GB 150—2011《压力容器》标准中的方法进行分析时,无法对带补强圈大开孔的压力容器进行补强计算。分别采用标准接触算法和绑定接触算法,利用ANSYS有限元分析软件对带补强圈大开孔接管结构进行应力分析和评定。结果表明,压力容器中带补强圈大开孔接管应力最大值一般分布在接管与筒体连接处,在计算过程中需考虑补强圈与筒体的接触作用,标准接触算法和绑定接触算法得到的计算结果相差不大。Due to technological and structural requirements, pressure vessels often needed to set up various large opening structures, which were beyond the scope of equal area method. When using the method of GB150- 2011 ＂Pressure Vessel＂ standard for analysis, it was impossible to carry out reinforcement calculation for pressure vessel with large opening of reinforcing ring. By using the standard contact algorithm and the binding contact algorithm, the stress analysis and evaluation of the large opening nozzle structure with reinforcing ring were carried out by using the ANSYS finite element analysis software. The results showed that the maximum stress of the large opening nozzle with reinforcing ring in the pressure vessel was generally distributed at the transition joint between the nozzle and the cylinder. The contact effect between the reinforcing ring and the cylinder should be considered in the calculation process. The calculation results obtained by the standard contact algorithm and the binding contact algorithm were not very different.
