Abstract
Abstract
Under the role of applied magnetic field, different values and directions of magnetic induction intensity will be produced in different sections of the magnetostrictive material (Terfenol-D) in GMA (giant magnetostrictive actuator). When mono-coil is used to measure the magnetic induction intensity of the magnetostrictive material, measures must be taken to reduce the influence of the coil on the magnetic induction intensity. The method proposed in this paper can accurately measure the magnetic induction intensity of magnetostrictive material, it uses multi-coils to create the most suitable near-zero magnetic field at the detecting points, so as to reduce the influence of the coils on the magnetostrictive material itself and realize the accurate measurement of magnetostrictive material’s magnetic induction intensity.
