Isolation and damping properties of magnetorheologic elastomers
Journal of Physics: Conference Series, 2009 This paper considers two systems based on a magnetorheological elastomer (MRE): a MRE isolator under a frequency varying harmonic excitation and a MRE Dynamic Vibration Absorber (DVA) mounted on a frequency-varying structure under a random excitation. It is shown that the commandability of the elastomer improves the isolation performances in the first ...

Application of a magnetorheological elastomer in an aviation structure [PDF]
, 2016 Magnetorheological elastomers have properties that can be altered by magnetic field. Many materials were invented more than 30 years ago, but their development and improvement over the past three decades has led to new, more varied uses of these ...

Magnetorheological Elastomers and Their Applications
, 2013 Magnetorheological elastomers (MRE) are smart materials whose modulus or mechanical performances can be controlled by an external magnetic field. In this chapter, the current research on the MRE materials fabrication, performance characterisation, modelling and applications is reviewed and discussed.

Investigation of tensile properties of RTV Silicone based Isotropic Magnetorheological Elastomers.
MATEC Web of Conferences, 2018 Magnetorheological elastomer (MRE) consists of an elastomer matrix and a Ferro-magnetic ingredient. The mechanical properties of MR elastomers can be reversibly controlled by applying a magnetic field of suitable intensity.
