Abstract: Based on the principle that the viscosity of electrorheological fluids changes according to the  electric field  intensity,the movement  law of damping vibration  controlled  in electrorheological fluids are investigated  by using  disturbance  method,the movement  equation  is  derived,and shift for frequency and shift for phase is derived.With the electric field intensity increases,the frequencies for angle are reduced;so with index’s square for electric field’s intensity,the amplitude of system’s vibration is reduced.For the same intensity of steady electric field and alternating electric field,the vibration is faster attenuated in the alternating electric field.While time amounts 1/E2ε,the vibration will be stopped.

Key words: electrorheological fluids, damping controlled, vibration
