【摘要】 通过在大秦线的线路试验,监测C_80BF型运煤专用敞车在实际运行过程中车轮踏面、闸瓦接触面温度,得出车轮踏面与闸瓦接触面作用对轮瓦温度及闸瓦性能的影响,以及车轮磨耗与温度的关系。本文旨在研究分析副构架式径向转向架在正常运行、制动和缓解时,轮轨、轮瓦作用形态,研究轮径差大小对踏面磨耗的影响。更多还原

【Abstract】 Through in Daqin line experiment,monitoring C_80BF type special purpose coal open top wagon wheel tread in the process of actual operation,the brake shoe contact surface temperature,it is concluded that the effect of the contact surface of wheel tread and brake shoe on wheel temperature and the influence of the brake shoe,as well as the relationship between the wheel wear and temperature.Vice framed the purpose of this paper is to study the radial bogie,braking and release in normal operation,the wheel/rail and wheel function form,and the wheel radius size effect on the wheel tread wear.更多还原
