1、高速列车的优点在于速度高,燃料省,安全可靠,服务优良。因此,高速列车从一开始就显示出了冃大的优越性。同普通列车相比,高速列车的性能大大提高。近来我国铁路系统瞄准世界铁路先进水平,运用后发优势,博采众家Z长,坚持原始创新、集成创新和引进消化吸收再创新,用短短几年时间,推动我国高速铁路技术走在世界最前列。随着铁路向高速化发展,列车的运行速度也达到了前所未有的水平,列车一旦发生故障必眾会带来严重的后果,因此列车运行状态实时监测与故障诊断变得更加重要。列车检测技术就是对列车运行过程屮的诸多因索进行检测,包括列车运行位置、列车运行速度、列车乘务信息等。通过检测可以为列车ri动控制系统提供列车列车运
2、行速度控制、列车运行间隔控制等基础安全信息。列车故障诊断是识别列车运行状态的科学,它研究的是列车运行状态在诊断信息屮的反映,其研究内容对列车运行的识别诊断、对其运行过程的检测以及对其运行发展的趋势的预测。本文主要介绍了我国高速列车检测与故障诊断的现状,以及高速列车检测与故障诊断的重要性及发展趋势进行了阐述,主要对动车牵引传动系统的故障进行了分析。关键词:高速列车检测故障诊断牵引传动系统ABSTRACTHighspeedtrainhastheadvantagesofhighspeed,fuelsaving,safeandreliable,excellentservice.Therefore
