Train wheel set monitoring system and train wheel set monitoring method

Abstract

The invention discloses a train wheel set monitoring system and a train wheel set monitoring method. The train wheel set monitoring system includes: a fault feature simulation module configured to simulate vibration data corresponding to a fault in a dynamic model of a large train system; module, which is configured to check the vibration data of the fault corresponding to the measurement point; the fault characteristic database module, which is configured to construct the fault characteristic database; the fault and vibration characteristic parameter mapping database module, which is configured to analyze the vibration in the fault characteristic database The vibration characteristic parameters are extracted from the data to form a mapping database; the fault inversion model module is configured to establish a fault and feature mapping function model for the mapping database; the monitoring module is configured to monitor the fault degree according to the mapping function model. The train wheel set monitoring system and the train wheel set monitoring method of the embodiment of the present invention can use the mapping function model to obtain the fault degree and monitor the detailed information of the fault degree in real time.

Description

technical field [0001] The invention belongs to the technical field of trains, and in particular relates to a train wheel set monitoring system and a train wheel set monitoring method. Background technique [0002] The wheel set is the core component of the running part of the train, and it is also the component with the most faults and the most difficult maintenance. The faults mainly include two types of wheel tread peeling and polygonal wear. Tread peeling refers to the phenomenon of metal peeling off damage and scale-like or crack-like thermal cracks on the tread circumference or part of the circumference of the wheel due to braking or wheel-rail rolling contact fatigue during operation. Polygonal wear refers to the wavy wear in the circumferential direction of the wheel tread during vehicle operation. Both will cause strong vibration and impact, induce strong vibration and noise, lead to accelerated fatigue of tracks, train profile parts, etc., and seriously affect the...

AI Technical Summary

Problems solved by technology

At present, there are relatively mature products for the fault monitoring system of the train running part based on vibration signals, but its products have the following shortcomings: 1. The fault early warning of the wheel is relatively elementary, and the frequency diagnosis is basically the main method, and the tread stripping cannot be realized. 2. It is difficult to arrange and transform the monitoring system; 3. It is necessary to install an additional early warning system, which is costly
