| 摘 要： | 采用区间分析方法针对目前还少有人研究的具有材料非线性的不确定结构系统进行分析计算,并针对计算结果易于扩张这一区间计算的主要缺陷,采用把区间函数计算和区间方程组的求解转化为以非确定参数为优化变量,以结构静态响应解为目标函数的全局最优化问题,进而得到静态解的区间边界值.计算中采用实数编码遗传算法求解全局优化问题.

| Abstract: | In this paper,moreover interval analysis method is used to analysis uncertain structure system with nonlinear material on which there is no much research yet.Because overestimation is one main limitation in interval computation,computation of interval function and solution of interval equations set are transformed into general optimization problems to determine the boundary of each interval element in the solution in this work.Genetic arithmetic of real number coding is used to solve general optimization problems. |

| Keywords: | uncertainty nonlinear material interval analysis general optimization genetic arithmetic |
