ACTIVE ENGINE MOUNT WITH PIEZOELECTRIC ACTUATOR AND METHOD FOR REDUCING VIBRATION OF ENGINE STRUCTURE USING SAME

摘要

The present invention relates to an active engine mount with a piezoelectric actuator and a method for reducing the vibration of an engine structure using the same capable of efficiently reducing the vibration generated in an engine structure by damping the vibration with a driving force of an opposite phase. The present invention provides the an active engine mount with a piezoelectric actuator which includes a body which includes an internal receiving groove with the open underside; the piezoelectric actuator which is arranged inside the receiving groove of the body; an elastic supporter which is joined to the piezoelectric actuator while covering the piezoelectric actuator; a supporting member which is arranged on the lower side of the body while being fixed to the elastic supporter and fixed to a lower supporting structure; a joining member which is connected to the engine structure while being joined to the supporting member and which transmits a reverse-phase driving force generated by the piezoelectric actuator; and a control unit which is electrically connected to the piezoelectric actuator and an accelerometer and a method for reducing the vibration of the engine structure using the same.;COPYRIGHT KIPO 2014
