| Abstract: | A detailed introduction to the existing theories and techniques of rail grinding and their application practices was presented.The interactions between rail grinding and rail rolling contact fatigue,rail wear,noise and rail lubrication,as well as their models,were discussed.Based on the existing economic models for rail grinding,a modified economic model was proposed,with the costs of depreciation of grinding equipment incorporated.Suggestions about researches in the future are presented: developing a compu... |
