바이모달 트램 곡선 선회폭에 관한 연구

다국어 초록 (Multilingual Abstract)

The train travels on the track and thus the rear wheels precisely follow the paths of the front wheels. On the contrary in the vehicles running on the road like automobiles buses and trucks the front wheels try to drag the rear ones toward them and across the inside of the curve. Off-tracking is defined as the radial offset between the path of the centerline of the front axle and the path of the centerline of the following axle. In the case of the bimodal tram with AWS(all wheel steering) the off-tracking decrease but the rear swing-out values increase because of the rear steering at the reverse phase angle. Thus in order to determine the swept path width maximum road width at the minimum turning radius off-tracking and swing-out should be considered for the bimodal tram. In this paper trajectory simulations were carried out for the various condition such as front steering front and rear steering and suppression of swing-out to optimize the swept path width.
