共轭复指数随机激励及有关响应分析

Conjugated Complex Exponential Random Excitation and Related Response Analysis

本文首先介绍共轭复指数随机函数。作为一种典型的随机激励模型,列举了它的工程应用背景。然后系统地叙述在这一激励下常参数线性系统响应(包括位移、速度、加速度响应)相关特性的解析公式。

A clear description of the conjugated complex exponential random function is given in this paper.As atypical random excitation model,the back-ground of its engineering applications is fully explored.The ana-lytical expressions for the correlation characteristics of random responses,inclcuding displacement,veloci-ty,and acceleration ones,of a time-invariant linear system under the above mentioned random excitation areintroduced systematically.
