Abstract

Disclosed is a rotation and axial-vibration damper with electro-rheological fluids. When a vibrator vibrates, rotating blades in the damper are driven to rotate by the aid of magnetic force, a piston in the damper is driven to move by the aid of the magnetic force and a spring, damping fluids flow through the rotating blades and a small circular through hole (damping hole) on the piston and simultaneously consume energy when the rotating blades rotate and the piston moves, and the viscosity of the electro-rheological fluids is changed by changing voltage between a positive plate and a negative plate according to the requirement on vibration control, so that the vibrator is individually or simultaneously controlled to rotationally vibrate around the damper and vibrate along the axis of the damper. As a dynamic seal is omitted, damping fluids are not easy to leak out of the damper.
