Abstract

The invention discloses a method for on-line in-situ calibration of a dynamic torque sensor, and relates to the technical field of torque sensor calibration. According to the main technical scheme, the method includes setting a magnetoelectric torque sensor on a shaft of a tested torque sensor, and the tested torque sensor is connected between rotation driving equipment and load equipment; starting the rotation driving equipment, setting a preset torque value for the rotation driving equipment, and recording a reading M0 of the magnetoelectric torque sensor and a reading Mi of the tested torque sensor; obtaining an error value delta M of the measured torque sensor by using a formula delta M = Mi-M0, wherein the precision of the magnetoelectric torque sensor is greater than that of the tested torque sensor. The technical problem that the torque sensor cannot be dynamically calibrated is solved.

Description

technical field [0001] The invention relates to the technical field of torque sensor calibration, in particular to an online in-situ calibration method for a dynamic torque sensor. Background technique [0002] The torque sensor is a precision measuring instrument for measuring various torques, speeds and mechanical power. It has a wide range of applications and is mainly used for: detection of output torque and power of rotating power equipment such as electric motors, engines, and internal combustion engines; detection of torque and power of fans, water pumps, gearboxes, and torque wrenches; railway locomotives, automobiles, tractors, and airplanes , Torque and power detection in ships and mining machinery; torque and power detection in sewage treatment systems; used in process industry and process industry testing. [0003] Since the torque sensor is a precision measuring instrument, it is necessary to calibrate the torque sensor regularly. At present, the calibration o...
