초록
Terfenol-D is one of magnetostrictive materials which have the property of converting the energy in magnetic fields into mechanical movement and vice versa. We designed and fabricated a linear magnetostrictive actuator using Terfenol-D. It has 25mm diameter and 100mm long. To grasp the characteristics of it, a series of tests were performed in the range of 50㎐ below. Induced-strain actuation displacements of the actuator measured by test and predicted by magnetic analysis agreed well. (omitted)
