摘要
本文对随机振动中的随机结构问题进行了理论分析,给出了具有多随机参数结构的随机振动响应的一阶矩和二阶矩的数学表达式。从而解决了随机振动中具有多结构随机参数的问题。其过程很容易实现为计算机程序。
In this paper, random structure problem in the theory of random vibration is discussed. Sevearl solutions is obtained for the mean, variance and covariance of dynamic response of structure including many random parameters. Nonlinearities due to material and geometrical effects are also included. The results derived are easily amenable to computer procedures.
