Negative stiffness honeycombs for recoverable shock isolation
Dixon M. Correa,Timothy Klatt,Sergio Cortes,Michael R. Haberman,Desiderio Kovar,Carolyn Conner Seepersad +5 more
TL;DR: In this paper, a negative stiffness honeycomb is fabricated in nylon 11 using selective laser sintering and its force-displacement behavior is simulated with finite element analysis and experimentally evaluated under quasi-static displacement loading.
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
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
Design, fabrication, and analysis of lattice exhibiting energy absorption via snap-through behavior
TL;DR: In this paper, an energy absorption lattice, comprised of multiple tetra-beam-plate unit cells with negative stiffness, was designed, fabricated by selective laser sintering method, and analyzed both numerically and experimentally.
Journal ArticleDOI
Mechanical Performance of Multidirectional Buckling-Based Negative Stiffness Metamaterials: An Analytical and Numerical Study.
TL;DR: The presented metamaterials are able to undergo multiaxial stress conditions while retaining the negative stiffness effect and energy-absorbing nature and possess abundant freedom of parametric design, which is potentially useful in shock and vibration engineering.

A curved-beam bistable mechanism
TL;DR: In this paper, a monolithic mechanically bistable mechanism that does not rely on residual stress for its bistability is presented, based on two curved centrally-clamped parallel beams, hereafter referred to as double curved beams.
Journal ArticleDOI
Extreme damping in composite materials with negative-stiffness inclusions
TL;DR: The experimental realization of this composite approach is described by embedding negative-stiffness inclusions of ferroelastic vanadium dioxide in a pure tin matrix, which exhibits extreme mechanical damping and large anomalies in stiffness, as a consequence of the high local strains that result from the inclusions deforming more than the composite as a whole.
Journal ArticleDOI
A study of a nonlinear vibration isolator with a quasi-zero stiffness characteristic
TL;DR: In this paper, a vibration isolator consisting of a vertical linear spring and two nonlinear pre-stressed oblique springs is considered, and the softening parameter leading to quasi-zero dynamic stiffness at the equilibrium position is obtained as a function of the initial geometry, pre-stress and the stiffness of the springs.
Journal ArticleDOI
Passive Vibration Isolation
TL;DR: In this article, the principles of design and means for realization of passive vibration isolation systems for real-life objects are discussed, and a special emphasis is given to effective techniques and methods that are not yet widely used in the practice of vibration isolation in industry.
