PROBLEM TO BE SOLVED: To provide a method for reducing a meandering flow that occurs in an L-shaped space formed by a space between a floor surface of a railway vehicle and the ground surface, and a space between a side surface of a railway vehicle and a tunnel wall surface, which is considered to be a cause of rocking of a railway vehicle, scattering of ballast, etc. that occur while a railway vehicle is running in a tunnel.SOLUTION: In a method for reducing a meandering flow that occurs in an L-shaped space (S) formed by a vehicle underfloor space (S1) between a floor surface of a railway vehicle 1 and the ground surface 2, and a vehicle side space (S2) between a side surface of the railway vehicle 1 and a tunnel wall surface 3, a moving separation plate 4 is provided to the L-shaped space (S) as meandering flow reduction means. The moving separation plate 4 is provided along the longitudinal direction of the railway vehicle at a lower corner part of the railway vehicle 1.SELECTED DRAWING: Figure 1

    【課題】鉄道車両がトンネルを走行中に発生する車両動揺やバラスト飛散等の原因と考えられる、鉄道車両の床面と地面との間の空間と、鉄道車両の側面とトンネル壁面との間の空間とで形成されるL字状空間に発生する蛇行流れを低減する方法を提供する。【解決手段】鉄道車両1の床面と地面2との間の車両床下空間(S1)と、鉄道車両1の側面とトンネル壁面3との間の車両側方空間(S2)とで形成されるL字状空間(S)に発生する蛇行流れを低減する方法において、L字状空間(S)に蛇行流れ低減手段としての移動分離板4を設け、移動分離板4は、鉄道車両1の下部コーナー部に、鉄道車両の長手方向に沿って設けられている。【選択図】図1
