A train wheel detection and maintenance system

Abstract

The embodiment of the invention discloses a train wheel detecting and maintaining system. The system comprises: a mechanical measuring device arranged on a track in a measuring area and for carrying out wheel-track contact force detection on passing train wheels, and obtaining wheel-track contact force data of the passing wheels; a wheel-track contact force data preprocessing device communicatively connected to the mechanical measuring device and for performing signal converting and amplifying on the wheel-track contact force data; a data storage device communicatively connected with the wheel-track contact force data preprocessing device and for storing a preprocessing result of the wheel-track contact force data; a data analysis device connected to the data storage device and configuredto analyze whether the wheels have defects or to predict whether the wheels will have defects according to the wheel pre-processing result of the wheel-track contact force data. The technical proposalof the embodiment of the invention can realize the real-time detection of the wheel and the effect of carrying out preventive maintenance on the wheel.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of wheel-rail detection, in particular to a train wheel detection and maintenance system. Background technique [0002] Wheels are the key components of trains, and real-time safety monitoring is crucial to ensure the safety of train operation. With the popularization of high-speed trains and urban rail trains in my country, the running speed and frequency continue to increase, and the accompanying defects of wheel out-of-roundness are becoming increasingly prominent. Wheel out-of-roundness is caused by wheel abrasion, tread peeling, tread protrusion, wheel polygonization, wheel A general term for phenomena such as eccentricity. It is the main excitation source that causes the impact vibration of the vehicle wheel-rail system, which will cause changes in the dynamic response of the wheel-rail system, and has a great impact on the driving stability, safety, comfort and the life of each c...

Problems solved by technology

However, static measurement not only needs to be carried out when the train is stationary, but also can only be discovered and dealt with after the wheels are out of round, which has already caused hidden dangers to driving safety and caused vehicle maintenance. and maintenance lag, which is not conducive to the driving safety of the vehicle, and at the same time affects the ride comfort of passengers, and also affects the service life of the wheel itself and the service life of other parts of the vehicle
