Noise and vibration suppressors
The Journal of the Acoustical Society of America, 2006In order to form a noise suppressor in a hose of e.g. a motor vehicle, modular portions are connected in series to define suppression chambers with particular noise suppression characteristics. Those characteristics are due to the volume of each chamber, to the size of the apertures from the chambers to the central duct of the suppressor, and ...

Dynamic vibration absorbers (DVA) are commonly studied for their advantage in controlling the low-frequency resonance peaks, but most relevant studies are still at the stage of theoretical innovation such as nonlinearity parameters and active control.

An active vibration suppressor for suppressing vibrations in structures, such as buildings, has an actuator attached to the structure and an extendable rod of the actuator attached to a seismic mass which is thus moved by the actuator. A sensor is attached to the structure adjacent to the actuator and connected to a compensated power amplifier which ...

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 ...

A novel rail corrugation suppressor using synergistic mechanism of vibration absorption and damping
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2022Rail corrugation increases the intensity of interaction between the wheel and the rail, make the vehicle and track vibrate more strongly, and increase the rolling noise. Based on the fixed corrugation wavelength mechanism, this paper determines the required corrugation wavelength to be controlled using field investigations.

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 ...
