摘要
本文介绍一种新的振动主动控制方法 ,在主动反馈中合理设计补偿器 ,把被动吸振器转换为带通吸振器 ,在给定频率范围内 ,放大频率 ,使所有这样的频率都发生谐振。如果把这样的吸振器连接到一个振体上 ,它能把带通范围内的频率全部吸收。该方法需要对吸振器质量的位移进行附加就地控制。本文描述了该方法的设计方法 。
A new concept for active vibration suppression with a so called bandpass absorber (BPA) is presented. A properly designed compensator in the active feedback converts the well-known passive absorber into a bandpass absorber. Such an absorber amplifies frequencies in a given frequency range, thus producing almost the resonance for all these frequencies. If such an absorber is attached to a bandpass range. The presented compensator design guarantees the stability of the system. The proposed concept needs an additional local control of the absorber mass displacement. The paper presents the idea, the design procedure, and the simulation results that prove the relevance of the solution.
