A comparison of two nonlinear damping mechanisms in a vibration isolator
(2013-02-04)
The vibration transmissibility characteristics of a single-degree-of- freedom (SDOF) passive vibration isolation system with different nonlinear dampers are investigated in this paper. In one configuration, the damper is ...
Novel active and passive anti-vibration mountings
(Academic Press Ltd Elsevier B.V. Ltd, 2012-03-26)
This paper investigates a novel design approach for a vibration isolator for use in space structures. The approach used can particularly be applicable for aerospace structures that support high precision instrumentation ...
On the detailed design of a quasi-zero stiffness device to assist in the realisation of a translational Lanchester damper
(2022-02-01)
A translational Lanchester damper is a device that adds damping to a structure at a point using a series combination of a viscous damper and a mass. The problem in the practical realisation of such a device is that a ...
On The Use Of The Wave Finite Element Method For Passive Vibration Control Of Periodic Structures
(Techno-PressDaejeon, 2016)
Recent Advances in Shock Vibration Isolation: An Overview and Future Possibilities
(2019-01-01)
Mechanical shock is a common problem that is present in many situations, such as ground motion, blast, explosions, crash, and impact. The development of passive, active, or adaptive control and isolation strategies for ...
Control of relative vibration between flexible appendages using passive and semi-active isolation
(Elsevier, 2017-12)
Relative vibration between two flexible subsystems can be detrimental to the performance of many engineering applications, such as optics-based instruments, machine tools, or adjacent industrial structures sharing piping. ...
Experimental analysis of active-passive vibration control using viscoelastic materials and extension and shear piezoelectric actuators
(SAGE PUBLICATIONS LTD, 2011)
Hybrid active-passive damping treatments combine the reliability, low cost and robustness of viscoelastic damping treatments and the high-performance, modal selective and adaptive piezoelectric active control. Numerous ...
Testing and performance of a new friction damper for seismic vibration control
(Academic Press Ltd - Elsevier Science Ltd, 2017-07)
In the last two decades, great efforts were carried out to reduce the seismic demand on structures through the concept of energy dissipation instead of increasing the stiffness and strength. Several devices based on different ...
Modeling and analysis of laminate composite plates with embedded active-passive piezoelectric networks
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2011)
The objective of this work is to present the finite element modeling of laminate composite plates with embedded piezoelectric patches or layers that are then connected to active-passive resonant shunt circuits, composed ...
Multimodal passive vibration control of sandwich beams with shunted shear piezoelectric materials
(IOP PUBLISHING LTD, 2008)
This work presents a performance analysis of multimodal passive vibration control of a sandwich beam using shear piezoelectric materials, embedded in a sandwich beam core, connected to independent resistive shunt circuits. ...
