DERIVATION METHOD, DERIVATION DEVICE, DERIVATION SYSTEM AND PROGRAM

To calculate the number of movable bodies that constitute a movable body traveling in a structure with a lower load.SOLUTION: Time sequence data which includes the physical quantity generated at an observation point in response to the travel of a formation movable body formed by one or more movable bodies in the structure is acquired; a temporary value which is a temporary value of the number of movable bodies that are organized into the formation movable body is acquired; the estimated amount of deflection of the structure generated at the observation point due to the passage of the formation movable body is derived on the basis of the temporary value, using a deflection model in the structure; and the number of movable bodies that are organized into the formation movable body is derived on the basis of comparison results of the time sequence data and the estimated amount.SELECTED DRAWING: Figure 33 【課題】構造物を移動する移動体にいくつの移動体が編成されているかを、より低負荷に求めることができないという課題があった。【解決手段】１つ以上の移動体が編成された編成移動体が構造物を移動することによる応答として観測点で生じる物理量を含む、時系列データを取得し、編成移動体に編成された移動体の個数の仮の値である仮値を取得し、仮値に基づいて、構造物における撓みのモデルを用いて、編成移動体の通過により観測点で生じる構造物の撓み量の推定値を導出し、時系列データと推定値との比較結果に基づいて、編成移動体に編成された移動体の個数を導出する。【選択図】図３３
