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.
