Vibration isolation performance of a beam clamped with torsional quasi-zero-stiffness isolator

Journal of Vibration and Control, 2023
Elastic beam structures connected by hinges are a common basic component of many mechanical systems. In this study, the nonlinear transverse vibration of a beam with one end free and the other end simply supported with a torsion spring is investigated.

A torsion quasi-zero stiffness vibration isolator

Journal of Sound and Vibration, 2015
Abstract A torsion vibration isolator with quasi-zero stiffness (QZS) is proposed to attenuate the transmission of torsional vibration along a shaft system, which also plays a role of coupling between shafts. A pre-compressed cam–roller mechanism is designed to provide torsional negative stiffness that counteracts with the positive torsion stiffness ...

A torsion–translational vibration isolator with quasi-zero stiffness

Nonlinear Dynamics, 2019
In this paper, a torsion–translational quasi-zero-stiffness (TT QZS) isolator with convex ball–roller mechanisms was proposed to attenuate the torsion and translational vibrations along shaft systems simultaneously. The mathematical model of the isolator was established, based on which the static characteristics of the isolator were analyzed and the ...

Analysis and design of a torsional vibration isolator for rotating shafts

Journal of Mechanical Science and Technology, 2019
A torsional vibration isolator which connects input and output rotating shafts was proposed in this study. For the design of the torsional vibration isolator, two dimensionless performance indices that quantify vibration isolation and response agility were defined.
