摘要

描述了被动减振器的时变扩展。利用李雅普诺夫稳定性理论证明了扩展型被动减振器与标准质量-弹簧-阻尼器被动减振器一样具有无条件闭环稳定性。与标准吸收器不同,扩展吸收器使用切换方案直接针对每个模式。最后给出了两种模态结构的计算机仿真和实验结果,验证了该结构的有效性。

Time Varying Passive Vibration Absorption for Large Flexible Structures Equipped with Few Inertial Reaction Devices
A time varying extension of the passive vibration absorber is described. Lyapunov stability theory is used to show that the extended passive vibration absorber possesses unconditional closed loop stability, as in the case of the standard mass - spring - damper passive vibration absorber. Unlike the standard absorber, the extended absorber uses a switching scheme to target each mode directly. Computer simulations and experimental work on two mode structures are given, which demonstrate the effectiveness of the extended absorber.
