Abstarct: The purpose of this research is to design, build and test a magnetorheological elastomer engine mount which is applied by horizontal and vertical forces, the elastomers used in the engine mount are in the shear regime. In this engine mount, two magnetorheological elastomers are used that their mechanical properties change in the presence of external magnetic field and also are immediately returned to the original state by removing the external field. After targeting to find the magnetic parameters needed to build the engine mount, simulator software was used. This software specifies the dimensions suitable for passing the magnetic field from the elastomers and then, considering the dimensions of the elastomers with the help of the SolidWorks software, so engine mount geometry is design for specific purposes. In the next step, we have to work on the assembly of parts and made instrument pieces baxsed on SolidWorks map. all of the assembled parts of the engine mount and oscillatory shear were tested in the presence and absence of a magnetic field and also at various frequencies. The results of the test are derived in the form of hysteresis charts in different frequencies and magnetic field extracted equivalent hardness (hysteresis gradient graph) and equivalent damping (enclosed hysteresis area) elastomers magnetorheological according to hysteresis diagrams and are compared to different frequencies and fields. it is shown that with increasing frequency and density of magnetic flux, the hardness and damping of magnetorheological elastomers increases.
