Journal ArticleDOI
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
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.
Journal ArticleDOI
Metastable modular metastructures for on-demand reconfiguration of band structures and nonreciprocal wave propagation.
TL;DR: This research elucidates the rich dynamics attainable through the combinations of periodicity, nonlinearity, spatial asymmetry, and metastability and creates a class of adaptive structural and material systems capable of realizing tunable bandgaps and nonreciprocal wave transmissions.
Journal ArticleDOI
A piezo-metastructure with bistable circuit shunts for adaptive nonreciprocal wave transmission
TL;DR: In this article, a nonlinear piezo-metastructure shunted with bistable circuits is proposed to achieve adaptive non-reciprocal elastic wave transmission, and the effect of the asymmetry factor on nonreciprocity properties is analyzed and the trade-offs between the forward transmission amplitude and the range of excitation with non-reward is identified.
