自增强圆筒的最优化设计

The Optimum Design of the Self-streng then Cylindrical Shell

本文以厚壁圆筒筒壁弹塑性交界面处的统计平均剪应力最小为目标函数,采用非线性规划寻优的黄金分割法对目标函数进行求解,迅速而准确地求得了自增强圆筒的最佳自增强半径 R_c 和最佳自增强压力

The minimum of th statistical mean shearing stress which is involved in th elastic- plastic boundary of a thick waU cylindrical shell is used as an objective function.The function is then solved by means of gold section of a non-linear optimization seeking method,and the self-strengthen optimum radius R_c and optimum pressure Pa of the self- strengthen cylindrial shell are obtained rapidly and precisely.
