摘　　要：以大型有限元分析软件ANSYS为工具,利用APDL语言建立了参数化模型,在研究了压力容器各部件之间不等厚过渡区域的应力强度分布规律的基础上,结合ANSYS优化设计模块,对不等厚过渡区域的尺寸进行了优化设计.得出了过渡区域的尺寸和结构最大应力强度之间的关系,找到了过渡结构的最优设计尺寸.结果表明,采用优化设计后的结构最大应力强度比设计前的结构下降了10.6%.A parametric model of the pressure vessel＇s transition zone was set up, using APDL language by conventional finite element software ANSYS. On the basis of analysing the distribution of transition zone＇ s stress intensity and taking advantage of the optimization design module of ANSYS, the dimensions of the transition zone were optimized. The relationship between the maximum stress intensity and the dimensions and a best design of the transition zone were prouided. The result shows that the maximum stress intensity in the best design can be reduced by 10.6% than before.
