Abstract:

The implementation process of rail profile grinding was described. The key links of target profile design， grinding mode design and result acceptance evaluation were analyzed. The design methods of each link were proposed and the relevant computer intelligent design program was developed. The on-site implementation effects were observed and analyzed based on actual cases. The results show that the optimization of the design methods for each key link of rail grinding can greatly improve the pertinence of rail grinding operation. The development of computer intelligent design program can greatly improve the design efficiency and implementation accuracy of rail grinding schemes. After the intelligent design methods were adopted in the Guangtong-Dali Line of Kunming Railway Bureau， the serious wear problems of small radius curve rail and locomotive wheel flange were effectively solved， the results of field test and theoretical analysis are basically consistent. The application of this method can effectively control the wear of rail and wheel， prolong the service life of rail and delay the wheel turning cycle.
