Analysis on Transverse Cracks Detection Capability of Rail Flaw Detection Vehicle

摘要: 针对钢轨探伤车高速检测能力问题, 结合我国钢轨探伤车的运用特点和核伤的检测原理, 对钢轨探伤车的轨头核伤检测能力进行了理论和应用分析, 并通过伤损试块和实际线路检测进行了验证。认为在目前的探伤车标准体系模式和运用管理模式下, 轨头核伤的检测灵敏度不低于《钢轨探伤管理规则》(铁运【2006】200号)中钢轨探伤仪对轨头核伤检测时设定的检测灵敏度。

Abstract: In this paper, the capability of the rail flaw detection vehicle on the rail head transverse crack detection is analyzed through considering the opplication features in china and the rail head transverse crack detection principles, and is verified by the reference block testing and the in-service line testing. We come to that under the Chinese operation management mode and under the Chinese standard system mode, the rail head transverse cracks detection sensitivity is not lower than that in “Rail Flaw Detection Management Rules”(China Railway Transport Bureau Managing Files ［2006］200).
