PROBLEM TO BE SOLVED: To easily calculate horizontal displacement of a rail with accuracy sufficient for practical use.SOLUTION: A position of a rail to a wheel 7 is subtracted from a value to be obtained by performing second-order integration to acceleration in the horizontal direction of the wheel 7. Thus, since meandering motion components of the wheel 7 is canceled, an influence of a gap between the rail R and a wheel flange 7B is excluded, and horizontal displacement is easily calculated with accuracy sufficient for practical use. |
