摘　　要：基于有限元应力分析方法,分析了应变强化压力容器在强化压力下,不同补强结构的容器封头与接管连接处应力强度水平和塑性应变量。结果表明,补强圈补强与厚壁接管补强最大塑性应变量都符合标准要求,但考虑在容器封头与接管连接处的应力强度、塑性应变分布的差异,应变强化压力容器开孔补强使用厚壁接管补强结构更加合理。Based on the finite element stress analysis method, stress intensity and plastic de- formation at the ioint zone of tube and head plate for a pressure vessel under strengthening pres- sure with different reinforcing structures were analyzed. The result shows the two reinforcing structures can meet the requirements of plastic deformation of strain strengthening pressure ves- sels, and considering the difference in stress intensity and strain distribution, the thick-wall tube reinforcement is more reasonable.
