Problems solved by technology

[0004] The above detection methods all process the parameters of a single wheel set by collecting multiple sensor signals, but fail to make a comprehensive detection and processing of various possible fault data of the wheel set
In addition, the existing electromagnetic ultrasonic transducer uses a single coil to transmit the acquisition signal, but this transmission mode is susceptible to electromagnetic interference, which is not conducive to the accuracy of wheel set fault data processing

Abstract

The embodiment of the invention discloses a fault dynamic detecting and data processing method and system of a wheel set, wherein the method comprises the following steps of obtaining the detection result after processing the acquired overall dimension data of the wheel set, the wheel abrasion data, the tread crack of the wheel set and material peeling defect data when the train is put in storage, wherein the detection result includes the detection result of the overall dimension data of the wheel set, the tread abrasion detection result and the tread crack and peeling detection results; and drawing the overall dimension detection curve of the wheel and the tread crack peeling detection curve according to the detection results. The centralized detection of various faults of the wheel set is carried out when the train is put in storage, and the overall dimensions, train abrasion and tread crack as well as the material peeling defect of the wheel set are correspondingly measured and calculated in combination with the light section method, the displacement method and an electromagnetic ultrasonic transducer, so that the detection centralized degree and integrity of the fault parameters are improved, and the comprehensive detection and processing technical effect of various possible fault data is achieved.

Description

technical field [0001] The invention relates to the technical field of train detection, and more specifically, to a data processing method and system for dynamic detection of wheel set faults. Background technique [0002] The wheel set is the part of the rolling stock that is in contact with the rail. The left and right wheels are firmly pressed on the same axle. The role of the wheel set is to ensure the running and steering of the rolling stock on the rail. , to reduce the wheel-rail interaction force and running resistance, the ellipticity and eccentricity of the axle journal and the wheel tread are strictly limited (the tread is the outer circumferential surface of the wheel in contact with the rail surface). [0003] The existing field of daily detection of surface defects of train wheels includes wheel tread scratches and out-of-roundness online dynamic detection devices, or wheel tread peeling defects with electromagnetic ultrasonic transducers for online dynamic det...
