Vibration Reduction of Transfer Feeder by Active Vibration Control

Abstract

Recently, transfer feeders, which are conveyance equipment for large-size press machines, have become larger in size and faster in speed for the elevation of productivity. For this reason, the stiffness of the structure has decreased, causing various vibration problems. To solve this problem, we proposed a method where the dynamic damper is located on the vibration transmission path from the objective vibration system to the vibration source. But the effect is not always sufficient to make the machine more accurate. Therefore we developed the active vibration control system, using the actuator located on the motion transmission path. The validity of this method is shown in the simulation and the result of the application to transfer feeder.
