单自由度振动系统对任意激励响应的仿真分析

The Simulation Analysis on the Response to the Arbitrary Excitation of Single-Freedom Vibration System

根据单自由度振动系统对单位脉冲激励的响应,利用杜哈梅积分公式可以求出系统对任意激励的响应,再用计算机对其进行仿真分析,结果直观明了,是一种非常有效的振动分析工具。

Based on the response to the unit impulse excitation of single-freedom vibration system, the response to arbitrary excitation can be obtained by using Duhamel integral formula. The result is very intuitional by emulating analysis, which can be considered a effective tool.
