This paper mainly describes working principle of an ER isolator. By building the mechanical lever model, performances of the isolator are theoretically analyzed and dynamically simulated, and the main factors influencing the ER isolator working properties are ascertained. In conclusion, it proves that the ER isolator has better isolation abilities in both of low and high frequency zones. It can avoid resonance and efficiently decrease the amplitude of the force transmitted. It is ideal for the isolation of multi-frequency vibrations of an engine.
