| Abstract: | The giant magnetostrictive material (GMM) is a new type of function material with giant strain,high response speed, high power density and great output force. The giant magnetostrictive actuator(GMA) instead of the traditional moment motor is able to enhance performance of a hydraulic control valve and its system, such as response and precision, so as to meet higher needs. The present studies on GMM application to hydraulic control valves were introduced. The key techniques such as heat compensation, micro displacement amplifying and nonlinear control were analyzed while using GMA. Two realizing projects of two stage electro hydraulic servo valve based on GMA were presented and their respective principles and characteristics were discussed. |
