Abstract

Purpose

The serious wear problem of heavy-haul freight vehicle wheels affects the safety and economy of vehicle operation. This paper aims to study wheel wear evolution law and the influence of line parameters on wheel wear of heavy-haul freight, and provide the basis for operation and line maintenance.

Design/methodology/approach

The wheel wear test data of heavy-haul freight vehicles were analyzed. Then a heavy-haul freight vehicle dynamic model was established. The line parameters influencing wheel wear in heavy-haul freight vehicles were also analyzed by the Jendel wear model, and the effects of rail cant, rail gauge, rail profile and line ramp on wheel wear were analyzed.

Findings

A rail cant of 1:40 results in less wheel wear; an increase in the rail gauge can reduce wheel wear; and when matched with the CHN60 rail, the wear depth is relatively small. A decrease of 9.21% in wheel wear depth when matched with the CHN60 rail profile. The ramp of the heavy-haul line is necessary to consider for calculating wheel wear. When the ramp is considered, the wear depth increases by 8.47%. The larger the ramp, the greater the braking force and therefore, the greater of the wheel wear.

Originality/value

This paper first summarizes the wear characteristics of wheels in heavy-haul freight vehicles and then systematically analyzes the effect of line parameters on wheel wear. In particular, this study researched the effects of rail cant, rail gauge, rail profile and line ramp on wheel wear.

线路参数对重型货运车辆车轮磨损的影响

目的重型货运车辆车轮磨损问题严重，影响了车辆运行的安全性和经济性。本文旨在研究重型货运车辆车轮磨损演变规律及线路参数对车轮磨损的影响，为运营和线路维护提供依据。然后建立了重型货运车辆动态模型。研究结果轨距为 1:40 时，车轮磨损较小；轨距增大可减少车轮磨损；与 CHN60 钢轨匹配时，磨损深度相对较小。与 CHN60 钢轨匹配时，车轮磨损深度减少了 9.21%。计算车轮磨损时需要考虑重载线路的坡道。考虑坡道时，磨损深度增加了 8.47%。本文首先总结了重载货运车辆车轮的磨损特征，然后系统分析了线路参数对车轮磨损的影响。特别是，本研究探讨了轨道坡度、轨距、轨道剖面和线路坡度对车轮磨损的影响。同行评议本文的同行评议历史见：https://publons.com/publon/10.1108/ILT-02-2024-0038/。
