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. The main technical solution of the present invention is: arranging the magnetoelectric torque sensor on the shaft of the measured torque sensor, connecting the measured torque sensor between the rotating drive device and the load device; starting the rotating drive device, and connecting the measured torque sensor The above-mentioned rotary driving device sets a predetermined torque value, and records the reading M of the magnetoelectric torque sensor 0 and the reading M of the measured torque sensor i ;Use the formula ΔM=M i -M 0 Obtaining an error value ΔM of the measured torque sensor; wherein, the precision of the magnetoelectric torque sensor is greater than the precision of the measured torque sensor. The invention solves the technical problem that the torque sensor cannot be calibrated dynamically.

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...
