Experimental Study of Magnetorheological Elastomer Vibration Isolator

The magnetorheological elastomer has a broader potential application due to overcoming the settlement, poor stability, sealing problems and other shortcomings of magnetorheological fluid easily. Firstly the magnetorheological elastomer is prepared, and then it is experimentally proved that the magnetic effect of magneto-rheological elastomers is occurred under magnet field and the stiffness can be also adjusted by controlling the density of field through performance experiments. In this paper, a squeeze mode magnetorheological elastomer vibration isolator and a test rig are designed, it has been shown that the natural frequency of vibration isolator is changed, and the effect of vibration isolation is preferable from the amplitude-frequency characteristic curves for vibration control experiments.
