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。
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.
