随机振动系统的时间域分析方法

Time Domain Analytical Method for Random Vibrating System

通过对随机激励下的单自由度和多自由度线性振动系统的激励与响应信号进行分析处理,从而在时间域内用确定性信号建立起了振动系统输入与输出之间的关系。

By analysis the random exciting signal and the random response signal of a Single Degree of Freedom (SDOF) or a Multi-Degree of Freedom (MDOF) of vibration system, this paper sets up the differential equation of motion between the input and the output in time domain for the system.
