Full accident.The lossless detection methods such as magnetic powder, infiltration, ultrasound are mostly used at present, these detection methods need artificial detection, Wu Fashi
Existing automatic detection, detection efficiency is relatively low, and because most rail working environments are complicated severe, artificial detection difficulty is larger, examines simultaneously
Facilities and equipment needs to suspend operating during survey, causes certain economic loss.By taking the detection of railway switch rail as an example, track switch steel
The characteristics of rail is that section width becomes narrow gradually, and pressure is uneven, and section width is narrower, and pressure is bigger, with process
In, easily there is section fatigue crack in rail, such as finds not in time, will when section crack expands beyond tread further up
The rail fracture serious accident that the train was derailed occurs.
The detection methods such as the magnetic powder, the infiltration that use at present detect rail tread section crack, although accuracy of detection is high, inspection
Needed before survey to rail tread carry out surface grinding process, detection efficiency is relatively low, moreover, on railroad turnout steel rail train by frequency compared with
Height is detected every time, all by influence train on time normal through.
