Pneumatic vibration isolator is achieved through either passive or active control system, which offers the simple and reliable means to reduce the vibration of a platform system due to a vibration environment. In this paper, a pneumatic passive vibration isolation system is designed and fabricated. The maximum amplitude in Bode plot of the pneumatic passive vibration isolation system is about 6Hz and the value of the transmissibility is 4. Using adaptive control, the improvement of the peak frequency is not effective but the transmissibility can be reduced to be the value 2. The ER fl uid exhibits dramatic and reversible phase change in the presence of the electric field. After applying the ER fluid, the characteristics of the system proposed in the paper are improved and investigated via computer simulation.
