This paper introduces a new type of vibration isolator --- electrorheological vibration isolator.It simplifies the structure of the system and builds the physical model and deduces the differential equation of motion.On the basis of theoretical analysis and performance curve simulation, The main factors influencing the working characteristics of ERA are theoretic research.Research shows that ERA has good vibration isolation in both low and high frequency range, effectively reducing the amplitude of transmission force and expanding the frequency range of vibration isolation, and has anti-system Resonance performance.
