A vibration isolation and vibration suppression device is presented. The device consists of an electromagnetic actuator and a magneto rheological fluid (MRF) rotary shear damper. In the device, the MRF damper supports a vibrating body. Since the body is connected to the base with large rigidity using the MR damper, vibrations are small when an exciting force acts on the body directly. When base vibrations occur, the electromagnetic actuator under the disturbance force cancellation control isolates vibrations, where the shear force of the damper is controlled to be small. This device can control both vibrations due to exciting force acting on the body and base vibrations without using a heavy vibration table. To validate the system, experimental tests have been performed, and it is clarified that this device works well. Especially, the transmissibility in low frequency region can be suppressed within one.
