Abstract
An active engine mount using a piezo actuator for a large vibrational amplitude is discussed. As a piezo actuator has a small displacement, the active mount requires a mechanism to increase the displacement of the piezo actuator to sufficiently counteract vibration.
This paper describes in detail the construction of the prototype and the background theory from which the increase in displacement was achieved. Secondary, it describes a proving test performed on an experimental device that simulates the transfer of vibration from the engine to the chassis through the piezo active mounts. Finally it reports the decrease in floor vibration achieved when a piezo active mount was installed on an experimental vehicle.
