Abstract

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.
