Alongside the development of high-speed rail, rail flaw detection is of great importance to
ensure railway safety, especially for improving the speed and load of the train. Several …

Continuous welded rails (CWR) are track segments welded together to form a continuous
miles-long track. With respect to mechanically-jointed rails, CWR are stronger, smoother …

Interstitial free (IF) steels, as third generation of deep drawing steel, are used in the
automotive industry for applications requiring good formability, strength and a superior …

Thermal buckling of continuous welded rail (CWR) has been a long-standing challenge for
the railroad industry because of the high derailment rate and the associated social …

Wheel burn can affect the wheel–rail contact state and ride quality. With long-term operation,
it can cause rail head spalling or transverse cracking, which will lead to rail breakage. By …

The paper presents a new concept for evaluation of surface damage of rails subjected to
long-term cyclic loading. A rail cyclically loaded during 20 years of traffic was examined by …

Despite proven effectiveness and accuracy in laboratories, the existing damage assessment
based on guided ultrasonic waves (GUWs) or acoustic emission (AE) confronts challenges …

设计搭建了基于磁巴克豪森噪声(Magnetic Barkhausen noise, MBN) 的钢轨白层无损检测系统,
打磨U75V 钢轨以预制白层, 使用1 Hz, 8 V 的正弦信号磁化打磨钢轨试样并收集表面产生的 …

Manufacturing processes such as welding cause residual stresses which exist in most steel
civil structures, causing plastic deformations without any external loads. This type of stress is …

Magnetic Field Leakage (MFL) is one of the prominent methods used to detect rail top
surface cracks. However, it has been shown that detecting narrow rail top cracks is a major …
