随机参数非线性系统的随机响应分析

Analysis on the random response in the non-linearsystem with parameter at random

应用摄动法和随机中心差分法 ,研究了具有随机参数的非线性系统在确定性荷载下的随机响应 ,得到了均方响应的一种近似迭代关系 .

The random response of the non-linear system with parameter at random under the determinate load are studied by using the perturbation law and central differential dividing law.The approximate relations of (repeated) replacement are responded at each side and the sensitivities as well as the statistical properties of (dynamic) response for antisymmetrically laminated composite plates with random parameters are analysed at the same time.
