Study on Giant Magnetostrictive Material with Design and Simulation of Displacement Magnifying Mechanism

Abstract:

In order to make full use of advantages of giant magnetostrictive material and to improve output characteristics of giant magnetostrictive actuator, displacement magnifying mechanism is designed based on flexible hinges. The design parameter of the flexible hinges and strength of material of flexible hinges are calculated. Based on the analysis and comparison, the statics and dynamics analysis was carried on by analytic method and ANSYS12.1 software,the input stiffness, magnifying multiple and the relationship between output displacement and load are calculated,and the stress analysis shows that the maximum stress of magnifying mechanism is less than the maximum allowable stress of materials. The resonance frequency,vibration modes and harmonic response of the mechanism were resulted by Finite element method, and the dynamics parameters of system are get.
