DISPLACEMENT ACQUISITION DEVICE, AND DISPLACEMENT ACQUISITION METHOD AND PROGRAM
PROBLEM TO BE SOLVED: To make it possible for a displacement acquisition device to acquire response displacement of a bridge when a railway vehicle travels with a simpler configuration.SOLUTION: A displacement acquisition device comprises: a static component storage part which stores a time series of a static component that is a component not depending on movement of a railway vehicle among time series of displacement of a bridge girder accompanied with passing of the railway vehicle; a displacement detection part which detects a time series of displacement of the bridge girder on the basis of at least either an acceleration measurement value or a speed measurement value of the bridge girder to be measured accompanied with passing of the railway vehicle to be measured; a dynamic component extraction part which extracts a time series of a dynamic component that is the remained component of excluding a static component possibly including an error from the time series of the displacement detected by the displacement detection part; a static component acquisition part which acquires the time series of the static component from the static component storage part; and, a synthesis part which synthesizes the time series of the dynamic component extracted by the dynamic component extraction part and the time series of the static component acquired by the static component acquisition part.
【課題】変位取得装置が、より簡単な構成で鉄道車両走行時における橋梁の応答変位を取得できるようにする。【解決手段】変位取得装置が、鉄道車両の通過に伴う橋梁の桁の変位の時系列のうち前記鉄道車両の運動に依存しない成分である静的成分の時系列を記憶する静的成分記憶部と、測定対象の鉄道車両の通過に伴う測定対象の橋梁の桁の加速度測定値または速度測定値の少なくともいずれかに基づいて当該桁の変位の時系列を検出する変位検出部と、前記変位検出部が検出した変位の時系列から、誤差を含み得る静的成分を除いた残りの成分である動的成分の時系列を抽出する動的成分抽出部と、前記静的成分記憶部から前記静的成分の時系列を取得する静的成分取得部と、前記動的成分抽出部が抽出した前記動的成分の時系列と、前記静的成分取得部が取得した前記静的成分の時系列とを合成する合成部と、を具備する。【選択図】図１
