摘 要：Because the passive mount could not meet the requirements of vibration isolation and noise reduction for vehicle,the semi active mount and active mount were considered as the developing trend of reducing vibration and noise.An active vibration control system consists of a sensor and an actuator together with a control unit.The development of the systems is often limited by the chosen actuator technology.This article list the common engine vibration control system actuator,analyzing their respective performance summed up their role in the control of vibration and trends.
