摘要
基于ANSYS静力屈曲分析和多目标拓扑优化,模拟了几种不同加强肋形状的不锈钢管在受到外压时的失稳临界载荷及变形状态;分析影响其外压稳定性的几个因素,并对相关参数进行优化计算,得到最佳壁厚值。
Based on ansys static buckling analysis and the multi-objective topology optimization,simulated the buckling critical load and deformation state on several forms of stainless steel pipe under external pressure;analyzed several factors affecting the stability of the compression,and optimized the relevant parameters, get the best thickness values.
