Abstract

To extend limited stroke of giant magnetostrictive actuator (GMA)

a mechanical amplifier with flexure-hinges was embodied

the actual amplification stroke ratio and dynamic behavior of the mechanical amplifier with flexure-hingers were studied using theoretical material mechanics

Lagrange's dynamical equation and finite element method. The magnetic-elastic coupled model of GMA with flexure-hinges amplifier was established based on the constituted model of Jiles-Atherton(J-A) model and quadratic model; the coupled model was simulated in the co-simulation environment of software AMESim&Simulink. A prototype of GMA with flexure-hinges amplifer was manufactured

followed by a series of dynamic performance tests. Both simulation and test result shows that the stroke of GMA with flexure-hinges amplifier reaches 0.4mm; the frequency bandwidth is above 100Hz and the effectiveness of the coupled model is validated.
