Abstract

The invention designs an ultrasonic radial detection calibration test block and a detection method for axle products for railway locomotives and vehicles, and the calibration test block is an assembly composed of 15 ultrasonic radial detection calibration test blocks with different diameters. The basic principle for manufacturing and using the ultrasonic radial detection calibration test block is as follows: a test block blank which is completely the same as a detected axle product in material and heat treatment state and is the same as or similar to the detected axle product in surface state and type size is adopted for manufacturing the test block, so that the accuracy of quantity value transmission during detection is ensured.

Description

technical field [0001] The invention relates to a (group) ultrasonic radial detection calibration test block for an axle product of a railway locomotive. Background technique [0002] Axle products for railway rolling stock are important load-bearing parts of rolling stock running parts. When the rolling stock runs on the rails, the axle is prone to fatigue defects under the joint action of its own load and the impact force between the wheel and the rail. When the axle fatigue fails, the bearing function of the axle will also fail, which seriously affects the efficiency of railway transportation and the safety of transportation. Usually, in order to ensure the reliable operation of rolling stock, strict requirements are put forward for the internal quality of axle products, so the non-destructive testing of internal defects of axle products is also particularly important. TB / T 1618-2001 standard applies to the ultrasonic testing of internal defects of axle products for rol...
