随着高速列车的发展和运营，状态检修成为提高轨道交通可靠性和安全性的重要途径。本文报道了一种可行性研究，利用脉冲涡流热成像成像的多裂纹所造成的滚动接触疲劳（RCF）。在回顾轨道检测和RCF裂纹的基础上，介绍了PEC热成像系统，并将其应用于多个滚动接触疲劳裂纹的成像。最后，对轨道在线检测的可能性进行了讨论。(C)2011年由Elsevier Ltd.出版
With the development and operation of high speed trains, condition based maintenance becomes an important approach for the improvement of reliability and safety of rail transportation. This paper reports a feasibility study using pulsed eddy current thermography for imaging multiple cracks caused by rolling contact fatigue (RCF). After reviewing rail track inspection and RCF cracks, a PEC thermography system is introduced and applied to the imaging of multiple rolling contact fatigue cracks. Potential on-line inspection for rail track is also discussed. (C) 2011 Published by Elsevier Ltd.
