This article describes the creation of an adjustable stiffness vibration isolator that employs magnetorheological elastomer (MRE) - a smart material - to reduce undesirable vibration. The initial phase involved the design of the vibration isolator, followed by magnetic circuit simulation. Finite Element Method Magnetics (FEMM) software was subsequently used to demonstrate the generation of magnetic fields within the vibration isolator by MRE samples. The selection of the housing material and the MRE thickness is deemed necessary to complement a sufficiently strong and homogenous magnetic field, which alters stiffness. The
magnetic circuit design is innovative and takes into account factors such as the wire type, size, and coil turns for
the optimal magnetic field. Lastly, the performance of the MRE vibration isolator is examined through analyses
of the various current inputs in the coil. The increase in the value of the input electric current is more effective
in modifying the raised stiffness value of the MRE-based isolator system.
