To provide a wheel diameter management method for a railway vehicle, which can highly accurately calculate a wheel diameter with a simple structure.SOLUTION: This wheel diameter management method for a railway vehicle (1) comprises: a first measurement step; and a calculation step. In the first measurement step, while the railway vehicle (1) travels on a rail (R), the height of an axle (232) is measured by using a sensor (30) installed inside the rail (R). In the calculation step, a wheel diameter is calculated on the basis of the axle diameter of the railway vehicle (1) and the height of the axle (232) measured in the first measurement step.SELECTED DRAWING: Figure 3

    【課題】簡易な構成で、高精度に車輪径を計算することのできる、鉄道車両の車輪径の管理方法を提供する。【解決手段】鉄道車両(1)の車輪径の管理方法は、第1測定工程と、算出工程と、を備える。第1測定工程では、鉄道車両(1)がレール(R)上を走行するときに、レール(R)の内側に設置されたセンサ(30)を用いて車軸(232)の高さを測定する。算出工程では、鉄道車両(1)の車軸径及び第1測定工程で測定した車軸(232)の高さに基づいて、車輪径を算出する。【選択図】図3
