The invention has the beneficial effects that:
because the bearing ring of the high-speed rail is inclined, and the sound paths of detection areas are different, flat-bottom holes with different depths are designed according to different detection areas, so that the requirement that the set detection system can cover the detected surface of the bearing ring within 4mm after the test block is verified is met; in addition, the size of a flat-bottom hole designed in the existing test block is phi 1mm, and the detection sensitivity requirement of the existing detection technology cannot be met, so that the diameter of all the artificial holes is designed to be phi 0.5mm, and the sensitivity of the system is verified; the test block designed by the invention can be used for manufacturing a DAC curve or a TCG curve and promoting the popularization and application of related detection technologies.
