摘要
动车组轮对是关系动车组运行安全的关键部件,车轮的轮辋轮辐缺陷直接关系到动车组运行的安全。在线移动式轮辋轮辐探伤设备(LU)对轮辋内部缺陷和车轮轮辐区域缺陷进行在线综合探伤,为动车组安全运行提供了工装保障。具体介绍了LU设备的应用背景、组成、原理,以及现场应用情况、存在的问题和改进建议。
The wheelset is a key component of safety operation of the EMU train.Spokes defects are directly related to the safety of train operation.Online mobile rim spoke testing equipment（LU） detects the internal defects and the wheel spoke rim region defect and provides tooling support for EMU safety.This article introduces the LU equipment application background,composition,principle,and the field application,existing problems and puts forward some improvement suggestions.
