GRINDING CONDITION DETERMINATION DEVICE FOR RAIL GRINDING CAR AND GRINDING CONDITION DETERMINATION METHOD FOR RAIL GRINDING CAR
To provide a grinding condition determination device for a rail grinding car and a grinding condition determination method for a rail grinding car, which can appropriately grind rails in curved sections.SOLUTION: A target rail cross-sectional shape selection unit 32 selects a target rail cross-sectional shape from among a plurality of candidate rail cross-sectional shapes P1 to P15 based on the rail cross-sectional shape with the maximum amount of wear in a curved section. A grinding condition determination unit 33 determines the grinding conditions for grinding the rail R to the target rail cross-sectional shape. The candidate rail cross-sectional shapes P1 to P15 are cross-sectional shapes of rail wear shapes corresponding to the curve radius, and the rail wear shape is calculated from a wear progression analysis.SELECTED DRAWING: Figure 1
【課題】曲線区間のレールに対してレール削正を適切に施工することができるレール削正車の削正条件決定装置、レール削正車の削正条件決定方法を提供することにある。【解決手段】目標レール断面形状選定部３２が、曲線区間の摩耗量最大レール断面形状に基づいて、目標レール断面形状を、複数の候補レール断面形状Ｐ１～Ｐ１５の中から選定する。削正条件決定部３３が、レールＲを目標レール断面形状に削正するための削正条件を決定する。候補レール断面形状Ｐ１～Ｐ１５は、曲線半径に対応するレールの摩耗形状の断面形状であり、レールの摩耗形状は、摩耗進展解析から算出されている。【選択図】 図１
