ultrasonic fatigue testing machine

Nov 29, 2020 · A GPM-30 fatigue machine was used to investigate the influence of surface ultrasonic rolling (SURT) on the rolling contact fatigue (RCF) life of D2 wheel steel. The experimental results present that the RCF life of the grinding processing sample is 4.1 × 105 cycles. During the RCF process, the flaking of the fine grain layer and high surface roughness of the grinding processing sample cause ...

Ultrasonic NDT testing equipment have been adopted to study the tracks and wheels for fatigue. \- The regular and sound diagnostics, coupled with the timely detection of rail defects at early ...
