Proposal of a Two Movers Linear Oscillatory Actuator for Active Control Engine Mounts

Active control engine mounts employing linear oscillatory actuators are mounted onto automobiles to reduce the frame vibration and noise. In conventional ACMs, the electric power consumption is high, and we clarify the causes of the high electric power consumption by dynamic simulation. Moreover, we propose a new LOA with two movers. The operational principle is described and the effectiveness of the ACM is verified using dynamic simulation.
