【摘要】 随着列车的普遍提速以及新的高速列车的出现,对轨道动态特性的要求也越来越高,同时也给负责轨道日常维护的铁路相关部门提出了新的课题。本文在分析轨道不平顺特性的基础上,提出了一套新的轨道动态测试方法,并介绍了基于这种方法研制出的轨道动态测试仪的硬件及软件设计,文章最后专门就测试中的关键技术——门限电压的设定作了必要的阐述。更多还原

【Abstract】 As the speed of train increases and the new high-speed-train appears, it becomes more and more request to know the dynamic characteristic of railway, and in the meantime the related departments taking charge of the daily maintenance of railway are faced with new problems. On the basis of analyzing the uneven character of railway, this paper brings forward new dynamic detecting method of railway, and introduces the hardware and software design of the dynamic railway detecting instrument basing on the new method, and finally explains the key detecting technique-designing the threshold voltage.更多还原
