【Abstract】 In the paper, the vibration property of viscoelastic piston cylinder operator is studied, which contains the electrorheological (ER) fluid and a common spring. The experimental results show that the amplitude of vibration decreases and the resonance peak moves to higher frequency as the strength of electric field increases. This effect is obvious at lower frequency band. Following the result, a controlled damper can be made up.更多还原
