摘要

The objective of this study is to explore the influence of grinding stone granularity on the grinding force and rail material removal behaviors using a rail grinding friction machine. The results indicate that with the increase in granularity, the grinding force, and friction coefficient in the grinding interface obviously increase, which brings about a rise in the hardness and grinding temperature-rise of rail specimens. The increase in the grinding stone granularity causes a fall in the grinding volume and surface roughness of rail materials and brings about stronger vibration in the grinding interface owing to different material removal mechanisms. In view of the experimental results, the optimization of grinding stone granularity is significant for improving the rail grinding efficiency and surface quality.
