The better mechanical properties of Electrorheological fluid (ERF) are critical for its engineering application. In this paper, the effects of electric field strength and circumstance temperature on steady flow characteristic of ERF are analyzed; the effects of electric field strength, vibration amplitude, vibration frequency and circumstance temperature on ERF's dynamic mechanical properties are investigated using orthogonal tests. In addition, the ERF damper of lathe tool slide worked on shear-mode is developed; the turning experiments with the damper are performed in order to validate the suppressive effect of vibration. The experimental results demonstrate that ERF dampers can decrease the machining vibration response effectively.
