Study of Resistance Strain-resistor Torque Sensor Based on Simscape Environment

Abstract

In order to resolve the problems of the torque sensor, including the principles and structure can not be reflected, the measurement results to be idealized and the noise can't be presented in the MATLAB/simulink simulation environment. The simulation model of train-resistor Torque Sensor consists of three modules: the strain axis module to realize transformation the torque to the strain, bridge module including four strain gauges, bridge output voltage. The model output is 0 to 5V voltage, measurement results contain Gaussian distribution errors, which make simulation system to better reflect the real objects, at the same time for more detailed study of the torque sensor and pave the way.
