To provide a configuration in which a wheel load can be constantly measured while a commercial vehicle is running, so that the running safety of a railroad vehicle can be evaluated in consideration of the aging of the vehicle and track.SOLUTION: A wheel load measurement device for an axis beam type dolly comprises: a rotation angle acquisition unit that acquires the rotation angle of an axis beam of an axis beam type dolly; a correlation storage unit that stores the correlation between the rotation angle of the axis beam and a wheel load; and a wheel load calculation unit that converts the rotation angle acquired by the rotation angle acquisition unit into the wheel load based on the correlation.SELECTED DRAWING: Figure 4

    【課題】車両や軌道の経年変化を考慮して鉄道車両の走行安全性を評価できるように、営業車の走行中に輪重を常時計測できる構成を提供する。【解決手段】軸梁式台車の輪重計測装置は、軸梁式台車の軸梁の回転角を取得する回転角取得部と、前記軸梁の回転角と輪重との間の相関関係を記憶した相関関係記憶部と、前記相関関係に基づいて、前記回転角取得部で取得された前記回転角を輪重に変換する輪重算出部と、を備える。【選択図】図4
