| 摘 要： | 本文用矩阵摄动法将随机参数结构的动力响应基本方程转换成容易求解的形式，导出了响应量统计特性计算公式，编制了相应的计算机程序。与ＭｏｎｔｅＣａｒｌｏ法和普通随机有限元法相比，本文所介绍的算法具有对原始信息量要求较少，计算量少，便于工程应用的特点。

| Abstract: | The vibration equations of structure with random properties are transformed into the simple forms to be solved,using the matrix perturbation theory,in this paper.The dynamic response statistics formulae are derived.The relevant program are written.Compared with the Monte Carlo method and stochastic finite element method,the method introduced in the paper has advantages of less original information to be provided,less computing to be done and convenient to apply to engineering problems. |
