Abstract:
PURPOSE: A defect detector of a wheel in a traveling train is provided to improve the signal-to-noise ratio by embedding transmitting/receiving coils in each EMAT(Electro-Magnetic Acoustic Transducer) in each case. CONSTITUTION: A defect detector contains a base, a first EMAT(300), a second EMAT(400), a protection container and a rotation supporting device. The base is combined between center supports of rails. The first and the second EMATs contain coils(330,430) and magnets. The coils transmit and receive supersonic waves against a wheel to be traveled through the rails by coating each metal thin film(331,431) on the surfaces of each sheet in a repeatedly curved shape. The magnets are installed under the coils. The protection box is installed on the base by including the EMATs. The EMATs are symmetrized by inclining downward while locating in a line through the traveling direction of the wheel. The rotation supporting device is installed inside the protection box for rotating the EMATs corresponding to the moving load of the wheel. The EMATs are located in a space portion in one side of the center support. Each coil is curved corresponding to the curvature of the wheel lengthwise and widthwise the rail. Thereby, a signal-to-noise ratio is improved by preventing the direction receiving of the supersonic waves without approaching to the surface of the wheel.
