Characterization of Magnetorheological Elastomer (MRE) Engine Mounts

Materials Today: Proceedings, 2016
This study presents simulation of Magnetorheological Elastomers (MREs) as engine mounts. A 4- parameter model is used to model the MRE mounts and the performance compared with passive or rubber mounts. Using relative displacements and force transmissibility at low frequencies and high frequencies respectively, the comparison show a 50% vibration ...

EPM–MRE: Electropermanent Magnet–Magnetorheological Elastomer for Soft Actuation System and Its Application to Robotic Grasping

IEEE Robotics and Automation Letters, 2021
Conventional soft robotic grippers have been developed based on soft pneumatic actuators or using smart soft materials, but they need external pressure sources, are easily deteriorated or used in millimetric-scale, which leads to increase of the independency, instability, and vulnerability.

Dynamic analysis of tapered laminated composite magnetorheological elastomer (MRE) sandwich plates

Smart Materials and Structures, 2016
In the present study, the dynamic performance of the sandwich plate with magneto rheological elastomer (MRE) as the core layer and tapered laminated composite plates as the face layers is investigated. Various MRE tapered laminated composite sandwich plate models are formulated by dropping-off the plies longitudinally in top and bottom composite layers

An experimental study on dynamic behaviour of a sandwich beam with 3D printed hexagonal honeycomb core filled with magnetorheological elastomer (MRE)

Smart Materials and Structures, 2022
Abstract Sandwich beams with an aluminium face sheet and a magnetorheological elastomer (MRE) of varying proportions of elastomer and magnetic particles (weight to weight)% filled in a honeycomb core of Nylon and Resin8000 are manufactured and experimentally analysed in this study. To evaluate the dynamic properties of sandwich beams,

Semi-Active Chatter Reduction for Robotic Machining Using Magnetorheological Elastomers (MREs)

2017 IEEE 7th Annual International Conference on CYBER Technology in Automation, Control, and Intelligent Systems (CYBER), 2017
Chatter is one of the major barriers for the robotic machining process. As the dominant vibration frequency of the chatter varies under different working conditions, MagnetorheologicaI elastomers (MREs) whose stiffness is adjustable is an ideal device to be used for chatter control.

Fabrication of biased-magnetorheological elastomers (B-MRE) based on magnetized ferromagnetic particles

Sensors and Smart Structures Technologies for Civil, Mechanical, and Aerospace Systems 2019, 2019
Magnetorheological elastomers (MREs), like MR fluids, exploit magnetic forces between ferromagnetic particles to produce a material with instantaneously adjustable properties of stiffness and damping with external magnetic fields. In MREs, the particles are a part of a structured elastomer matrix, and an external magnetic field is applied to achieve an

A hybrid magnetorheological elastomer-fluid (MRE-F) isolation mount: development and experimental validation

Smart Materials and Structures, 2015
With the aim of improving micro-vibration isolation, a hybrid magnetorheological elastomer-fluid (MRE-F) mount with variable stiffness and damping is presented. The proposed mechanism combines a magnetorheological elastomer stiffness unit with a magnetorheological fluid damping unit in a parallel connection.

FE2 simulations of magnetorheological elastomers: influence of microscopic boundary conditions, microstructures and free space on the macroscopic responses of MREs

International Journal of Solids and Structures, 2020
Abstract In the current work, the response of heterogeneous magnetorheological elastomers (MREs) which are loaded by external magnetic fields in the absence and also in the presence of free space is studied. A fully-coupled two-scale finite element computational homogenization procedure is used to derive the material response at the macro-scale from ...

A new type of electromagnetic system for magnetorheological elastomer (MRE)-based base isolation system

Sensors and Smart Structures Technologies for Civil, Mechanical, and Aerospace Systems 2019, 2019
Magnetorheological elastomer (MRE)-based base isolation system has been proposed to compensate for the drawbacks of the existing passive-type base isolation system. MRE is one of smart material with magnetorheological (MR) effect that can change the stiffness and damping ratio in real time when the magnetic field is applied.

A tunable quasi-zero-stiffness vibration isolator (QZS-VI) with magnetorheological elastomer (MRE)

Smart Materials and Structures
Abstract This paper presents a field-tunable quasi-zero stiffness vibration isolator (QZS-VI), which is beneficial for broadening the frequency bandwidth for low-frequency mitigation. The proposed QZS-VI was constructed by embedding a magnetorheological elastomer (MRE) device into an X-shaped QZS-VI system, which fulfills the tuning ...
