| 摘 要： | 轨道车辆轮对是否需要镟修的传统测量方法操作繁琐，不利于日常检修。利用轮缘厚度及踏面高度两个参数设计了能同时对轮对踏面磨耗量超限和轮对轮缘磨耗量超限做出灯光提示的接触式便携警报装置，给出了机械设计方案和针对轮对踏面及轮缘磨耗量超限的判断方法，并对警报装置测量误差进行了分析。该装置操作方便，能可靠地对轮对是否需要镟修作出判断。

| Abstract: | The conventional method for measuring whether rail vehicle wheel set needs turning is complex and inconvenient for routine maintenance. In this paper,by using the parameters of flange thickness and tread height,a portable alarm device is designed which can simultaneously detect tread and flange over-wear and make lighting tips through contact detecting. The mechanical structure,operating method and measurement er-ror of the device are analyzed respectively. The proposed device is proved easy to operate and can reliably deter-mine whether the wheel set needs turning or not. |
