초록
In fabricating linear actuator using the GMA(Giant Magnetostrictive Alloy : Terfenol-D). the clamping unit is needed to accumlate each displacement from the GMA rod. Two types of the clamping unit (one is using piezoelectric device and the other electromagnetic farce) were made and tested. From the result of the experiment, we conclude that the electromagnetic clamping unit has advantages over the piezoelectric clamping unit.
