摘要

In order to improve the accuracy of the capacitive grating torque sensor, this paper proposes a calibrationmethod of the capacitive grating torque sensor based on phase difference. The main idea of this calibrationmethod is phase difference, which uses the universal dividing head to generate a high precision torsion angleand make the still sleeve rotate. This calibration method does not load torque, but produces a high precisionrelative rotation torsion angle as the standard input, which can achieve the same torsional effect to realizethe torque sensor calibration. Firstly, the structure and basic principle of the capacitive grating torque sensoris described. Secondly, the relationship among torque, torsional angle and phase difference are introduced.Thirdly, the calibration system is introduced. Finally, the calibration experiment is carried out and theexperiment results are analyzed by MATLAB software to obtain the calibration error. The experiment resultshows that the calibration method of phase difference is correct.
