Wheel set is one of the most important components for railway vehicles. Comprehensive NDT wheel set ensuring system and corresponding equipment have been developed in some countries to ensure the safety of wheel set. LU automatic ultrasonic inspection system for in-service wheel set has been widely applied in Chinese high speed train, which uses advanced phased array ultrasonic technology to inspect...
Rail is one of the vital components of the railway system. Rail flaw detection plays an important role in ensuring the safety of railway transportation. Nowadays, rail inspection system based on conventional ultrasonic technology can't meet the practical application needs well due to the problems of low-detection coverage rate and inconvenient to change ultrasonic angle. To solve those problems, a...
The quality of wheel is especially important for the safety of high speed railway. In this paper, a new ultrasonic array inspection method, the Full Matrix Capture (FMC) and Total Focus Method (TFM) algorithm, has been studied and applied to the high speed railway wheel inspection, especially in the wheel web from the tread. The Total Focusing Method (TFM) which processing image with the data set...
