摘　　要：为有效降低储罐大角焊缝结构处的应力强度水平,将GB 50341—2014《立式圆筒形钢制焊接油罐设计规范》中只给出取值范围的边缘板外伸长度、边缘板内伸长度、大角焊缝在罐壁内侧的焊缝长度设置为输入可变参数,将大角焊缝结构处的最大应力强度设置为输出参数,优化目标设置为大角焊缝结构处的最大应力强度最小。经ANSYS响应面优化分析,最大应力强度在选择不同的结构参数时变化范围较大,优化分析可以确定出多参数的最佳组合,提出了优化和结果选择建议。In order to effectively reduce the stress intensity level at the large fillet weld structure of the storage tank,the three parameters of the outer extension length of the edge plate,the inner extension length of the edge plate,and the weld length of the large fillet weld on the inner side of the tank wall,which are only given in the GB 50341—2014“Code for design of vertical cylindrical welded steel oil tanks”,were set as input variable parameters.The maximum stress intensity at the large fillet weld structure was set as output parameter,and the optimization goal was set to minimize the maximum stress intensity at the large fillet weld structure.Through ANSYS response surface optimization analysis,it is found that the maximum stress intensity varies widely when selecting different structural parameters.Optimization analysis can determine the optimal combination of multiple parameters,and suggestions for optimization and result selection are proposed.
