Experimental study of self-adaptive remnant vibration suppression for flexible structure with interior inlay viscous fluid unit

Abstract

This paper investigates a novel self-adaptive remnant vibration suppression technology for a flexible structure using an interior inlay viscous fluid unit method (IVFUM) via experiment. The IVFU is embedded in the flexible structure that can efficiently and self-adaptively suppress the remnant vibration of the engineeering flexible structure. To envaluate the effect of the IVFUM, the self-adaptive remnant vibration suppression experiments for the IVFU Euler beam were carried out in the fixed frequency excitation and the rotation excitation. The experimental results demonstrated that the IVFUM has the validity and self-adaptability for the engineeering flexible structure remnant vibration suppression under certain conditions.
