Modeling of a magnetorheological elastomer-based isolator
A variable stiffness and damping isolator (VSDI) is designed and developed employing MREs. A double lap shear test has been carried out to characterize two MRE based VSDIs under quasi-static shear loading. A phenomenological model which can capture the behavior of the VSDI is developed and related parameters are identified using experimental data. Both experimental and theoretical modeling resu...
متن کاملExperimental study on vibration characteristics of sandwich beams with aluminum skins and magnetorheological elastomer cores
Magnetorheological elastomer (MRE) material consisting of a natural or synthetic rubber filled with micron sized iron particles is a smart material whose properties can be controlled by a magnetic field. In this paper, experimental study on the dynamic characteristics of an MRE core embedded sandwich beam is carried out. Frequency responses from experimental results on MRE cored sandwich beams ...
متن کاملAdaptive Sliding Mode Control for Civil Structures Using Magnetorheological Dampers
An adaptive sliding mode controller for vibration control is proposed in this paper for structures embedded with magnetorheological (MR) dampers. Civil structures and buildings are liable to damages during earthquake periods. The application of structural control methodologies is important in order to suppress vibrations due to seismic phenomena and dynamic loading. The use of sliding mode cont...
متن کاملElectrical resistivity mechanism in magnetorheological elastomer
Magnetorheological elastomers (MRE) are smart materials made by aligning magnetic microparticles inside a liquid polymer. Once the polymer is cured, this anisotropic structure is kept, giving to the composite new properties such as a large change of electrical resistivity with applied pressure. In order to understand the conduction mechanism in such composite, the influence of pressure on the e...
متن کاملSemiactive Nonlinear Control of a Building Structure equipped with Magnetorheological Dampers
This paper proposes a novel design framework for semiactive nonlinear fuzzy control system that is a linear matrix inequality (LMI)-based systematic design methodology for nonlinear control of building structures employing magnetorheological (MR) dampers with multi-objective requirements. Multiple optimum linear controllers are designed in terms of LMIs such that global asymptotical stability a...
