振动控制的特征结构配置

Eigenstructure Assignment for Vibration Control

本文针对“非对称系统的动态特性需由它的频率,左、右模态向量共同决定”的原理,为克服普通极点配置法仅能配置频率的缺点,提出了频率,左、右模态向量的特征结构配置法。文中的计算结果表明:用它配置的反馈能满足对结构频率,左、右模态向量的设计要求。

According to the principle that the dynamic characteristics of an unsymmetricsystem must be determined together by its frequency and left,right modal shape,the author gives an eigenstructure assignment of locating frequency and its left,right modal shape for overcoming the weakness of common method which can onlylocate its frequency.The results presented in this paper show that the feedbackgained by this method can satisfy the demand of frequency and left,right modalshape designed.
