摘要

Wheels are one of the key parts of train. Rolling contact fatigue cracks caused by frequent rolling contact with steel rails will seriously damage the safety of wheels. Non-destructive testing of wheels is essential to ensure the safety of train operation. Therefore, this paper has researched on the dynamic detection of wheel tread cracks based on eddy current pulsed thermography (ECPT). In this p...
