DISPLACEMENT ACQUIRING APPARATUS, DISPLACEMENT ACQUIRING METHOD, AND PROGRAM
PROBLEM TO BE SOLVED: To provide a displacement acquiring apparatus of a simpler configuration that can acquire response displacements of bridges when rail cars are running.SOLUTION: A displacement acquiring apparatus comprises: a displacement detecting unit that detects the time series of displacement of bridge girders ensuing from the running of rail cars on the basis of at least either of the measured acceleration or the measured speed of the girders; a component extracting unit that extracts from the time series of the displacement the time series of static components, which are components not dependent on the motion of the rail cars; a correction quantity acquiring unit that acquires a correction quantity for the time series of the static components on the basis of extreme values of the static components in the time series; and a correcting unit that corrects the time series of the displacement of the girders detected by the displacement detecting unit on the basis of the correction quantity acquired by the correction quantity acquiring unit.
【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前記桁の変位の時系列を検出する変位検出部と、前記変位の時系列から、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抽出する成分抽出部と、前記静的成分の時系列における極値に基づいて、当該静的成分の時系列の補正量を求める補正量取得部と、前記補正量取得部が取得した補正量に基づいて、前記変位検出部が検出した前記桁の変位の時系列を補正する補正部と、を具備する。【選択図】図１
