Structural design of giant magnetostrictive actuator
Source abstract
Abstract
Structural parameters of giant magnetostrictive actuator (GMA) have a greater impact on its output characteristics and how to design them is related to give full play to the material characteristics. On the basis of analyzing working principle of GMA, this paper respectively designs and optimizes the structural parameters of exciting coil, magnetic circuit, preload device and temperature control system. The initial best working conditions are achieved by research on static experiments. The experiment results show that this GMA has better static and dynamic output characteristic, which further improves GMA design theory and expands its applications.
