摘要

Traditional online wheel-set ultrasonic inspection method and inspection technology can not meet the new requirement of High Power Locomotive wheel-set online. In this article, features of locomotive wheel and defect distribution are analyzed, and a more strictly online inspection requirement is put forward. Based on which, an optimized multi arrangement of phased array and conventional ultrasonic probes is studied to perform a non destructive testing for wheel flange, wheel rim and wheel disk. Ultrasonic beam coverage and inspection performance are simulated by CIVA software and confirmed by reference wheel and real High Power Locomotive wheel online.
