With the development of science and technology, coupled with the continuous lowering of the mass of the car itself, the problems of noise、vibration、harshness (NVH) caused by engine vibration attracted more people's attention. This paper firstly clarifies the concept and principle of magneto rheological mounts and then explores the fuzzy control and simulation of vibration isolation of magneto rheological mounts in order to provide references for the related researchers. Concept and Principle of

... Magneto Rheological Mounts Concept. Magneto rheological fluid is a kind of controllable fluid under magnetic field can achieve a substantial increase in viscosity, and showed the yield phenomenon of solid, MRF is continuous and reversible regulation, reflect the time in milliseconds, easy to control, widely used in hydraulic suspension using liquid inertia in the flow passage the increase of engine suspension
