Abstract

The invention discloses an electromagnetic coupling ultrasonic automatic detection device and method for a wheel tread and a wheel rim. The electromagnetic coupling ultrasonic automatic detection device for the wheel tread and the wheel rim comprises an electromagnetic coupling surface wave probe, an electromagnetic coupling line-focusing incident body wave probe, a multi-way switching device, a duplexer, a radio frequency large-power impulse transmitter, a weak signal filtering and amplification device, a data acquisition card, an industrial control computer and a movement control device. By adopting the electromagnetic coupling ultrasonic automatic detection device and method for the wheel tread and the wheel rim, disclosed by the invention, the problem of realizing non-contact and coupling-agent-free detection of defects of the wheel tread and the wheel rim of a railway passenger train on an under-floor wheel lathe is solved.

Description

technical field [0001] The invention relates to the technical field of electromagnetic coupling ultrasonic detection, in particular to an automatic detection device and method for electromagnetic coupling ultrasonic of wheel tread and rim. Background technique [0002] When railway locomotives, passenger cars and EMUs are running, the wheels roll continuously on the rails, and their treads and rails form a pair of friction pairs. Due to the complex force of the wheel and the harsh operating conditions, it is easy to cause wear and cracks on the tread and rim, tread peeling, abrasions and other faults, which aggravate the unsafe operation of the vehicle. When the wear reaches a certain limit, it must be rotated. Shave the wheel tread. However, turning the wheel tread will inevitably reduce the thickness of the wheel rim. When the thickness is too thin, its strength will be reduced, resulting in the generation of internal cracks in the rim or the expansion of original defects...
