摘要
建立于钢轨横裂纹扩展模型,参照探伤结果和分析结果,推断横裂纹的扩展情况。在安全、经济的前提下提出了钢轨的适宜探伤周期。
The model of transverse cracking development in rail is established,and with reference of the flaw detection result and analysis result,the development of transverse cracking is concluded.The appropriate period of flaw detection for rail is put forward on the premise of safety and economy.
