Mechanism study and design of electrodynamic vibration suppressor
International Journal of Applied Electromagnetics and Mechanics, 2014In this paper, an electrodynamic vibration suppressor is proposed that can be used to suppress the main component of structural vibrations. This suppressor includes three main parts: an electrodynamic actuator, a power amplifier and a vibration controller. The intrinsic characteristics of the electrodynamic actuator were studied.

Ultrafast multistability in miniature photomechanical vibration suppressors
SPIE Proceedings, 1996It is well known that light has the ability to carry large amounts of information by virtue of its high intrinsic bandwidth and transmission speed. We report on a new class of mechanical fiber devices that are powered by light. In particular, we show that a sensor, logic unit, and actuator function can be built into a mesoscopic polymer optical fiber ...

A MIMO vibration suppression system with multi electrodynamic suppressors
International Journal of Applied Electromagnetics and Mechanics, 2016A multi-in-multi-out (MIMO) electrodynamic vibration suppression system based on global-local control strategy is established in this paper. The system has a structure composed of an upper layer and a lower layer. The lower layer employs a MIMO vibration suppression algorithm to suppress local vibration by using several eclectrodynamic vibration ...

Nonlinear Dynamics, 2021
Vortex-induced vibration (VIV) is a self-excited and self-limited flow-induced vibration phenomenon of importance for both the academic and the technological communities. Particularly for the offshore engineering scenario, VIV plays an important role in the structural fatigue analysis. Hence, VIV suppression is a relevant topic.

Dynamic analysis of periodic vibration suppressors with multiple secondary oscillators
Journal of Sound and Vibration, 2018Abstract A periodic vibration suppressor with multiple secondary oscillators is examined in this paper to reduce the low-frequency vibration. The band-gap properties of infinite periodic structure and vibration transmission properties of finite periodic structure attached with secondary oscillators with arbitrary degree of freedom are thoroughly ...
