PROBLEM TO BE SOLVED: To provide a creation method for a rolling stock and track interaction analytic model having a suitable split number which can suppress a sudden change with rail discretization.SOLUTION: In a creation method for a rolling stock and track interaction analytic model used for performance evaluation by computer-simulating railway structures or railway components during a travel of a rolling stock travelling over long rails in an advancing direction along the same, in the case of medium and small models where the number of analytic points of the number of utilization nodes or the number of elements used for analysis is less than predetermined, 20 or more are selected for the number of element splits of the rails to perform performance evaluation. In the case of large models where the number of the analytic points exceeds predetermined, 8 or more are selected for the number of element splits of the rails, and a predetermined band blocking filter based on a dominant frequency calculated from node gaps of the rails, travel speed of the rolling stock and coupling distances is used for filter processing to perform performance evaluation.SELECTED DRAWING: Figure 8

    【課題】レールの離散化に伴う急激な変化を抑制することのできる適当な分割数を有する車両・軌道相互作用解析モデルの作成方法を提供する。【解決手段】長尺のレールの上をこれに沿った進行方向へ向けて走行する車両の走行時における鉄道構造物や鉄道部材をコンピュータでシミュレーションして性能評価する際に使用される車両・軌道相互作用解析モデルの作成方法であって、解析に用いられる利用節点数や要素数等の解析点数が所定以下の中・小規模モデルの場合は、前記レールの要素分割の数は20以上が選択されて性能評価が行われ、その解析点数が所定を超える大規模モデル場合は、そのレールの要素分割数は8以上が選択されるとともに、そのレールの節点間隔、車両の走行速度及び締結間距離から算出される卓越振動数に基づく所定の帯域阻止フィルタを用いてフィルタ処理して性能評価が行われる。【選択図】図8
