依据运行于鹰厦线北端(鹰潭至邵武区间,该处属于山区多小弯道及大坡道的线路)的东风_4型机车,改装 ST_2型磨耗形踏面车轮后的实测磨耗数据,进行了分析研究。结论是,不论轮缘涂油与否,磨耗形踏面对减缓东风_4型机车轮缘的磨耗,都取得了显著效果,对减缓踏面磨耗也非常有效。文中还根据实测的钢轨外形,以弹性约束轮对为例,从理论上分析了磨耗形踏面车轮之所以能改善轮缘磨耗的机理。此外,还对进一步减缓轮轨磨耗提出了建议。 According to the data of DF4 type locomotive running on the northern end of Eagle Line (Yingtan-Shaowu section, which belongs to the small curve and ramp in mountainous area) Analysis. The conclusion is that no matter whether the rim oiling or not, the wear-and-tear tread has obvious effect on slowing the wear of the rim of DF_4 locomotive and is also very effective in reducing tread wear. Based on the measured rail profile and the elastic constraint wheelset as an example, the paper analyzes the mechanism of wear wheel on the worn tread wheel theoretically. In addition, the wheel and rail wear is further proposed.
