Many vibration isolators, for example, passive vehicle mounting devices, have fixed rigidity. This article presents the development of an adjustable stiffness engine mount based on the magnetorheological elastomer (MRE) to reduce engine vibration. The development of the first MREs vibration isolator was to design the engine mounting, and then to simulate a magnetic circuit. The choice of housing material and the thickness of the MRE is considered to complement a sufficient and uniform magnetic field to change the stiffness. The innovative magnetic circuit design includes the type and size of the wire and the number of turns of the coil for optimal magnetic field. Finite Element Method Magnetics (FEMM) software was used to demonstrate the effectiveness of electromagnetic circuits in generating magnetic fields through MRE samples. Finally, influenced by the various current input in the coil, the performance of the MRE vibration isolator is investigated. The input electric current whose value increases is more useful to change the increased stiffness value of the MRE-based isolator system.
