A torsion–translational vibration isolator with quasi-zero stiffness
Nonlinear Dynamics, 2019In 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 ...

Recent Advances in Quasi-Zero-Stiffness Vibration Isolation Systems
Applied Mechanics and Materials, 2013The quasi-zero-stiffness vibration isolation system has witnessed significant development due to the pressing demands for low frequency and ultra-low frequency vibration isolation. In this study, the isolation theory and the characteristic of the quasi-zero-stiffness vibration isolation system are illustrated.

Spectrum reconstruction of quasi-zero stiffness floating raft systems
Chaos, Solitons & Fractals, 2016Abstract 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.

Study on Semi-Active Control of Quasi-Zero-Stiffness Isolator
2018 10th International Conference on Intelligent Human-Machine Systems and Cybernetics (IHMSC), 2018Because the precision instrument is more sensitive to low frequency vibration, higher requirements are put forward for vibration control, and quasi-zero-stiffness isolator with semi-active control is proposed. Firstly, the basic structure of quasi-zero-stiffness is introduced, and the static characteristics of the quasi-zero-stiffness isolator are ...

Pressurized Origami Structure for Programmable Negative and Quasi-Zero Stiffness
Volume 5B: 40th Mechanisms and Robotics Conference, 2016This research investigates the nonlinear pressure-induced stiffness characteristics of an origami structure associated to its large amplitude folding. Such structure consists of origami tubes that are formed by stacking and connecting Miura-Ori sheets along their crease lines, so that one can apply pressure to achieve autonomous folding and generate ...

Active Control of Quasi-Zero-Stiffness Vibration Isolator with Variable Load
International Journal of Structural Stability and DynamicsQuasi-zero-stiffness (QZS) isolator has great application potential in the field of low-frequency vibration isolation due to its high-static and low-dynamic (HSLD) nonlinear stiffness characteristic, but it is precisely this characteristic that makes it very sensitive to load changes.
