| 摘 要： | 本文提出了一个离散系统动态载荷识别的时域方法。将动载荷识别问题完全归结为求解Voterra第一类积分方程的正解问题,进而获得了比例阻尼系统和一般粘性阻尼系统动态载荷的识别计算模式。最后采用数值逼近解法进行的仿真实例说明,方法是有效的。

| Abstract: | This paper is intended to provide a time domain method of identification of dynamical loads for discretisized vibration systems. It transforms the problem of load identification into that of solving a first kind Volterra integral equation. The computational formulations for identification of dynamical loads on system with either proportional damping or general viscous damping characters are presented. Some simulation examples are givea by using numerical approximate solutions. The effectiveness of the method offered is verified. |
