SELECTION METHOD OF RAIL CORRECTIVE GRINDING METHOD, AND CORRECTIVE GRINDING METHOD SELECTION SYSTEM
To provide a selection method of a rail corrective grinding method for optimizing and improving the efficiency of rail corrective grinding work by a classification method of a rail cross-sectional shape which is hardly affected by the measurement accuracy of rail cross-sectional shape data and a method for selecting an optimum pattern among existing corrective grinding patterns by the classification method, and a selection system for the rail corrective grinding method.SOLUTION: A selection method of a rail corrective grinding method has: a contour shape measurement step of measuring at least a contour shape in a rail transverse cross-sectional direction; a design value acquisition step of acquiring a design value of the contour shape in the rail transverse cross-sectional direction; and a superposition step of superposing the contour shape measured in the contour shape measurement step and the design value; a design difference area calculation step of calculating a design difference area between the contour shape and the design value; and a corrective grinding pattern selection step of obtaining an evaluation index of the cross-sectional shape from the design difference area and selecting a corrective grinding pattern corresponding to the evaluation index.SELECTED DRAWING: Figure 2
