ABRASION AMOUNT CALCULATION SYSTEM, SLIT LIGHT IRRADIATION DEVICE, AND ABRASION AMOUNT CALCULATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an abrasion amount calculation system for facilitating the measurement of the abrasion of a rail.SOLUTION: The abrasion amount calculation system includes: slit light sources 22a and 22b for radiating slit light from above of a rail 9; and a display unit 21 for displaying a reference figure as a two-dimensional figure having at least a first point existing at a predetermined position on a plane orthogonal to the longitudinal direction of the rail, a second point existing at a position different from the first point in a predetermined axial direction, and a third point existing at a position different from the first point in an axial direction orthogonal to the predetermined axial direction.SELECTED DRAWING: Figure 1
