Design and experiment of a high-static-low-dynamic stiffness isolator using a negative stiffness magnetic spring
TL;DR: In this paper, a negative stiffness magnetic spring (NSMS) is employed to reduce the resonance frequency of the linear isolator, and the effect of the geometric parameters of the magnets on the stiffness characteristic of the NSMS is analyzed.
Journal ArticleDOI
Simulated and experimental studies on a high-static-low-dynamic stiffness isolator using magnetic negative stiffness spring
TL;DR: In this paper, a magnetic vibration isolator with the feature of highstatic-low-dynamic stiffness (HSLDS) is developed, which is constructed by combining a magnetic negative stiffness spring (MNSS) with a spiral flexure spring (SFS) in parallel.
Journal ArticleDOI
Analytical study of a quasi-zero stiffness coupling using a torsion magnetic spring with negative stiffness
TL;DR: In this paper, a torsion magnetic spring (TMS) composed of two coaxial ring magnet arrangements in repulsive configuration is employed to produce negative Torsion stiffness to counteract the positive stiffness of a rubber spring.
Journal ArticleDOI
A Stewart isolator with high-static-low-dynamic stiffness struts based on negative stiffness magnetic springs
TL;DR: In this article, the negative stiffness magnetic spring (NSMS) was employed to construct high static low dynamic stiffness (HSLDS) struts to reduce the resonance frequency of the Stewart isolation platform.
