An integrated design of quasi-zero stiffness mechanism

Journal of Mechanical Science and Technology, 2016
Nonlinear Quasi-zero stiffness (QZS) mechanisms were studied to overcome the weakness of linear isolators. This paper presents an integrated design of the QZS mechanism. First, various types of QZS vibration mechanisms are analyzed and a generalized model for QZS mechanisms is derived.

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 ...

Spectrum reconstruction of quasi-zero stiffness floating raft systems

Chaos, Solitons & Fractals, 2016
Abstract Chaos control can be utilized to reform the response spectra of a dynamic system, potentially useful for the acoustic reconstruction of underwater vehicles. Introduction of the quasi-zero stiffness (QZS) isolators into the chaotification system can greatly reduce the emission of vibration signals from vehicles.
