Abstract
This paper presents a hybrid rubber mount with magnet to isolate effectively the vibration in vehicle, forklift, and so on. The hybrid mount does not have any controller of the magnetic force. Dynamic stiffness of the mount is reduced by only magnetic suction according to the applied magnetic field and damping coefficient increased. Performance of conventional rubber mount with using electromagnet has been investigated by MTS Tester. The governing equation of the hybrid mount was derived and verified by comparison with experimental and theoretical results. The equation can be used practically and usefully in the design of the mount and analysis of the mounting system. The hybrid mount provides excellent performance in vibration isolation and its structure is very simpler than active with controller and a semi-active mount with a functional fluid. Furthermore, production cost of the mount using permanent magnets is very lower than that of the active mount with electromagnets. Therefore, commercial potential of the mount is very high.
