Vacuum characteristics of magnetorheological elastomers

Journal of Physics: Conference Series, 2019
Abstract A model of gas evolution from the surface layer of a magnetorheological (MR) elastomer, which is a promising material for use in vacuum systems, is described. The results of research of the partial composition of gases exhaled from the MR elastomer for different heating temperatures depending on the pumping time are given.

Dynamic properties of magnetorheologic elastomer

Rakenteiden Mekaniikka, 2007
Machinery and buildings often have to be protected from vibrations. The needed reductionof dynamic response can be achieved efficiently with semi-active isolation. One way to usesemi-active isolation is to install vibration isolators between the base and the object to beprotected and control the dynamic properties of these isolators.
