| 摘 要： | 本文基于神经网络控制算法,研究了结构变频率特性主动控制方法,构建了控制系统整体框架,推导了整个控制系统的算法。同时,搭建了悬臂壳结构变频率特性主动控制实验台,利用附加在悬臂壳结构上的激振器,进行壳体表面多个位置的振动控制即结构变频率特性主动控制,从而完成与目标预设频谱的逼近,实验证明了该方法的可行性。

| Abstract: | Based on neural network control algorithm, this paper investigates the active control method of Structural variable frequency characteristic. The framework of the control system is constructed. The algorithm of the control system is derived. The experimental system of structural variable frequency characteristic for a cantilever shell structure is constructed. With multiple vibration exciters attached to the cantilever shell structure surfaces, the vibrations of multiple points on the shell structure surface is controlled. The predetermined spectra are well approximated via this active vibration control approach. The feasibility of the method is confirmed by the experiment. |
