Self-Adaptive Suppression of the Euler Beam Remnant Vibration Using the Interior Inlay Viscous Fluid Unit Method

Abstract:

In this paper a novel self-adaptive remnant vibration suppression method using interior inlay viscous fluid unit (IVFUM) has been investigated. The IVFU is imbedded in the flexible structure, that can self-adaptively reduce the flexible structure remnant vibration efficiently. In order to evaluate the effect of the IVFUM, the self-adaptive vibration suppression experiment for the IVFU Euler beam in the fixed frequency excitation and the rotating excitation were carried out.. We proposed the SDOF damping system model combined with the nonlinear least square fitting method to process the rotating remnant vibration attenuation signal and identify the rotating IVFU Euler beam modal parameters. Finally, it is demonstrated that the IVFUM for the remnant vibration suppression effect of the flexible Euler beam is efficient under certain conditions after experimental and numerical analysis.
