Carbody Lateral Displacement of Railway Vehicle According to 2nd Lateral Damper and Track Characteristics
철도차량 2 차 횡댐퍼 및 궤도특성에 따른 차체 횡변위 변화 연구
Abstract
In railway vehicle, riding comfort depends mainly on the secondary lateral damper and track condition. When the damping force of lateral damper becomes abnormal condition or the track condition is worse, the running stability and ride comfort of the railway vehicles go down. In addition, the lateral motion of carbody is increased. Therefore, the lateral motion of carbody is reviewed carefully by considering lateral damping force and track condition of the railway line in design stage. In this study, the lateral displacement of carbody was studied in accordance with lateral damping force and track condition. The target vehicle is EMU for subway line.
