| 摘 要： | 以钢轨圆盘代替钢轨，设计一种模拟钢轨被动打磨方式的实验平台，研究被动磨削方式下磨削压力和磨削速度对磨削力、磨削温度、磨削效率及钢轨表面粗糙度的影响。实验结果表明: 在60～80 km/h范围内，随磨削速度增大，切向磨削力、表面粗糙度减小，磨削温度升高、磨削效率增大；在120～320 N范围内，随磨削压力增大，磨削温度升高、切向磨削力增大、磨削效率增大、表面质量下降。

| Abstract: | The influence of pressure and speed on some grinding performance of passive rail grinding,namely the force,the temperature,the efficiency and the rail surface roughness,was studied on a test platform simulating passive grinding by replacing normal rail with rail disk.The results show that the increase of grinding speed in the area of 60 to 80 km/h,results in the decrease of grinding force and surface roughness and the increase of grinding temperature and grinding efficiency.It is also found that the increase of grinding pressure,from 120 N to 320 N,leads to higher temperature,larger force,higher efficiency and worse surface quality. |
