Design and test of an adjustable quasi-zero stiffness device and its use to suspend masses on a multi-modal structure
(2021-05-01)
In some applications, such as ground vibration testing in the aerospace industry, it is of interest to observe the modal behaviour of a slender structure while it is statically loaded. One way of statically loading such a ...
On the effects of mistuning a force-excited system containing a quasi-zero-stiffness vibration isolator
(Asme, 2015-08-01)
Nonlinear isolators with high-static-low-dynamic-stiffness have received considerable attention in the recent literature due to their performance benefits compared to linear vibration isolators. A quasi-zero-stiffness (QZS) ...
An investigation into the isolation performance of mono-and bi-stable systems
(2014-01-01)
Motivated by the need for improving the isolation performance, many research studies have been performed on isolators with nonlinear characteristics. Based on the shape of their phase portrait, such devices can be configured ...
On the detailed design of a quasi-zero stiffness device to assist in the realisation of a translational Lanchester damper
(2022-02-01)
A translational Lanchester damper is a device that adds damping to a structure at a point using a series combination of a viscous damper and a mass. The problem in the practical realisation of such a device is that a ...
A note on non-linear phenomena in a non-ideal oscillator, with a snap-through truss absorber, including parameter uncertainties
(2013-03-01)
This work considers the vibrating system that consists of a snap-through truss absorber coupled to an oscillator under excitation of an electric motor with an eccentricity and limited power, characterizing a non-ideal ...

On the shock performance of a nonlinear vibration isolator with high-static-low-dynamic-stiffness
(Elsevier B.V., 2014-04-01)
The vibration isolation characteristics of a high-static-low-dynamic-stiffness (HSLDS) isolator, which has geometrically nonlinear stiffness, have been well established both theoretically and experimentally in the recent ...
