To enhance the accuracy of abnormality diagnosis by enabling identification of an abnormal section while expanding a diagnosis target range of a railway vehicle.SOLUTION: An abnormality diagnosis device includes: an actuator command unit for commanding an actuator to vibrate a vehicle; a transfer characteristic calculator for calculating the vibration transfer characteristics to a second member from a first member from a first detection value of vibration characteristics of the first member of the vibrated vehicle and a second detection value of vibration characteristics of the second member of the vibrated vehicle; and an abnormality determination unit for determining the presence or absence of the abnormality of the vehicle based on the vibration transfer characteristics calculated by the transfer characteristic calculator.SELECTED DRAWING: Figure 1

    【課題】鉄道車両の診断対象範囲を拡げながら異常部位の特定を可能とすると共に、異常診断の精度を高める。【解決手段】異常診断装置は、車両を加振するようにアクチュエータに指令するアクチュエータ指令器と、前記加振された車両の第1部材の振動特性の第1検出値と前記加振された車両の第2部材の振動特性の第2検出値とから、前記第1部材から前記第2部材への振動伝達特性を算出する伝達特性演算器と、前記伝達特性演算器で算出された前記振動伝達特性に基づいて前記車両の異常の有無を判定する異常判定器と、を備える。【選択図】図1
