To provide an inspection system, an inspection device and an inspection method which enable abnormality in bogies to be easily identified before the bogies are more damaged.SOLUTION: An inspection system according to an embodiment of the present invention is configured to inspect a bogy comprised of: a plurality of side beams extending in the longitudinal direction and arranged in a laterally separated manner; and a transverse beam connecting the plurality of side beams. The inspection system includes one or more sensors and a position location unit. The one or more sensors are installed in either the plurality of side beams or the transverse beam, and detect an elastic wave. The position location unit identifies a beam in which the elastic wave has occurred or locate the occurrence source position of the elastic wave, on the basis of the elastic wave detected by the one or more sensors.SELECTED DRAWING: Figure 4

    【課題】損傷が大きくなる前段階で台車における異常を簡便に特定することができる検査システム、検査装置及び検査方法を提供することである。【解決手段】実施形態の検査システムは、前後方向へ伸びて、左右方向へ離間して配置される複数の側梁と、前記複数の側梁を連結する横梁とで構成される台車の検査を行うための検査システムである。検査システムは、1以上のセンサと、位置標定部とを持つ。1以上のセンサは、前記複数の側梁、又は、前記横梁の少なくともいずれかに設置され、弾性波を検出する。位置標定部は、前記1以上のセンサによって検出された前記弾性波に基づいて、前記弾性波が発生した梁を特定、又は、前記弾性波の発生源位置を標定する。【選択図】図4
