Abstract

The structure of a Galfenol torque sensor is designed based on the inverse magnetostriction effect, the thickness and grid width of the Galfenol patch are optimized through Comsol finite element simulation. The experimental platform is built according to the simulation results. the deformation of the sensitive element using a grid structure is increased by 9.82% compared to a thin plate structure; Compared to not widening the bottom of the magnetic choke, the stress on the bottom of the magnetic choke is reduced by 54%. The research in this paper shows that the sensor has high precision in small range of torque measurement, which provides reference for torque sensor.
