Abstract

The invention discloses a transmission shaft torque calibration method, comprising the following steps: 1) installing the transmission shaft to be tested on a test stand; 2) installing a strain gauge wireless measuring system on the transmission shaft; 3) applying Torque, the corresponding voltage value is output through the strain gauge wireless measurement system; 4) The torque calibration model of the transmission shaft is established, and the calibration coefficient is obtained by solving. Through the calibration method disclosed in the invention, the torque of the transmission shaft can be calibrated conveniently, quickly, accurately and reliably.

Description

technical field [0001] The invention relates to the technical field of transmission shaft detection, in particular to a transmission shaft torque calibration method. Background technique [0002] Torque measurement is an important part of the actual working load detection and test parameter monitoring of shaft parts. When carrying out the load test and related tests of the automobile transmission shaft, it is necessary to calibrate the torque of the transmission shaft, and obtain real-time transmission shaft according to the calibration results. and load information on the drive train. At present, the static torque calibration method is mostly used for the torque calibration of the transmission shaft, and the standard weight is loaded step by step on the static torque calibration platform designed by the principle of leverage to calibrate the transmission shaft. Some also use a standard torque wrench to test several fixed values, and then draw a fold (curve) line, and calcu...
