To reduce an inspection time for an inspection to estimate the position of a defect.SOLUTION: The method for a nondestructive inspection according to an embodiment includes the steps in which: a plurality of sensors set in a carriage supporting a vehicle detects an elastic wave generated when the vehicle is moved up or down by a lifting member inserted between the vehicle and the carriage; and an evaluation device estimates the position of a defect in the carriage on the basis of the elastic wave detected by the sensors.SELECTED DRAWING: Figure 1

    【課題】欠陥の位置を推定する検査の検査時間をより短縮する。【解決手段】実施形態の非破壊検査方法は、車体を支持する台車に設置された複数のセンサが、前記車体と前記台車との間に挿入された持上げ部材により前記車体を昇降させるときに発生する弾性波を検出するステップと、評価装置が、前記複数のセンサにより検出された弾性波に基づいて、前記台車の欠陥の位置を推定するステップと、を含む。【選択図】図1
