| 摘 要： | 介绍了北美铁路运输技术中心(TTCI)正在开发的轮/轨界面管理(WRIM)模型.WRIM考虑了运行条件、车辆动力学性能以及轮/轨接触特性对轮/轨界面的影响.WRIM可以进行静态轮/轨接触分析和动态轮/轨相互作用趋势分析.本文还给出了运用WRIM减少轮/轨界面处能量消耗的研究过程,并预测了轨道的打磨周期.

| Abstract: | Transportation Technology Center,Inc.（TTCI） is developing the Wheel/Rail Interface Management（WRIM） model.WRIM considers the effects of operating conditions,vehicles dynamic performance,and wheel/rail contact features on the wheel/rail interface.WRIM can be used to perform static wheel/rail contact analysis and dynamic wheel/rail interaction trend analysis.This paper presents examples of applying WRIM to investigate the process for reducing the energy consumed at the wheel/rail interface and to predict rail grinding intervals. |
