Abstract

The three-dimensional simulation model of torque sensor is established by finite element, the overall structure of the sensor is optimized, and the magnetic flux distribution and output voltage of the optimized structure are simulated, and the output data are obtained. Finally, a experimental platform is built to measure the static characteristics of the torque sensor. the sensitivity is 0.688 mV/Nm when loading, 0.597mV/Nm when unloading. The error of simulation output data is compared with the actual experimental data. When loading, the error is about 4.36% and the accuracy is 6.31%. During unloading, the error is about 5.14% and the precision is 6.59%. This paper shows that the torque sensor based on Galfenol alloy has a considerable effect, which provides reference for torque sensor.
