| Abstract: | The structure and the characteristics of a magnetostrictive actuator made from giant magnetostrictive material in China were investigated. The magnetic circuit in the actuator was optimized by a 2D axisymmetric model with FEM. The experimental results showed that under certain conditions of preloaded press and bias magnetic field, a satisfied static characteristic was obtained. |
