Fault detection method of gearbox

Abstract

The embodiment of the invention provides a fault detection method of a gearbox. The method comprises: a train running parameter and a gearbox temperature parameter of a to-be-detected gearbox are inputted into a gearbox fault detection model; and a fault detection result of the to-be-detected gearbox is outputted, wherein the gearbox fault detection model is obtained by training based on a train running parameter sample of a gearbox sample, a gearbox temperature parameter sample and a fault detection result sample. According to the method provided by the embodiment of the invention, the trainrunning parameter and the gearbox temperature parameter are inputted into the gearbox fault detection model and the fault detection result of the to-be-detected gearbox is outputted, so that the real-time effective online detection of the gearbox is realized, the real-time performance and convenience of running data monitoring of the train are improved, and the stable operation of the D-series high-speed train and the railway system are guaranteed.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of train safety detection, in particular to a gearbox fault detection method. Background technique [0002] The rapid development of high-speed EMU trains has laid a good foundation for the construction of high-speed railways, and at the same time puts forward new requirements for vehicle operation and maintenance departments. As a key component of high-speed rail transportation machinery, the gearbox body is very necessary to ensure its safe service performance and prevent serious failure. [0003] Common faults of gearboxes include gear damage, bearing damage, broken shaft, oil leakage and high oil temperature, etc. Among them, the bearing is the most important part in the gearbox, and its failure often causes catastrophic damage to the gearbox. In addition, during the operation of the bearing, the ring and the surface of the rolling element are subjected to repeated alternating...
