Vibration Isolation News Today

Future missions to the moon and Mars must address many challenges, including preventing loss of bone and muscle tissue in astronauts. Research on the International Space Station is helping to address this challenge.

Fancy biking the streets of Denmark while in space? A new VR headset on the ISS lets an astronaut do just that, to expand on mental health studies in orbit.

This paper proposed and prototyped a metamaterial isolator with periodic structure based on magnetorheological elastomer (MRE) and magnet spring. With acoustic metamaterial structure, the proposed metamaterial isolator can generate a stop-band, which means the vibration over specific frequency can't be transferred and will be isolated effectively. Then, with the control of MRE stiffness, the cut-off frequency of the stop-band is tunable, which makes the isolator potential to be adapted to d...

This article explores the precision of microbalancing and how this is enhanced by negative-stiffness vibration for various high-resolution applications.

This paper presents a new elastic origami-inspired structure with quasi-zero-stiffness (QZS) characteristics to provide effective low-frequency vibration isolation performance. The geometric structure of the origami mechanism is first introduced, followed by the establishment of its mechanical model through the integration of elastic joints with compression springs. The derived strong nonlinear stiffness characteristics of the elastic origami mechanism are conducive to exploring a QZS isolator w...

The Nancy Grace Roman Space Telescope is being developed by NASA to be launched in 2027. In order to get the best results possible, vibration isolation has been used to optimize image clarity.

As a representative nonlinear system, Duffing oscillator has wide applications in the field of vibration control. This paper concentrates on the analytical jump criteria problem for a class of Duffing systems based on the concave-convex property. The mechanical model of Duffing-type isolators subjected to various excitations is firstly presented. The defined single critical jump point (SCJP) is proved to be an inflection point based on the concave-convex property of the dynamic response. Moreove...
