摘　　要：为提高火车渡轮的装载量和装卸效率,提高火车渡轮引桥对船型的适应性,设计了一种以短轨构成,并在相邻接短轨之间预留一定伸缩间隙的柔性轨道。推导了柔性轨道段在进行船岸对接时的整体弯曲变形几何关系和轨道间隙变化量的计算公式,计算了柔性轨道在不同弯曲变形状态下各设计参数的对应数值。从几何变形关系及其数值分析方面证明了该柔性轨道的可行性。A new type of flexible railway consisting of short rails with expansion and contraction spaces between them was developed to help increasing the capacity and loading/discharging speed of train ferries as well as the compatibility between train ferries and ferry bridges. In this paper, we present the geometric relationship of and the calculating formulas of expansion or contraction of the space between two adjoining rails in the flexible railway being bended to link two railways that are not in a straight line. The numerical values of the displacement and the shape parameters of the flexible railway when bending it to different shape are also listed here. The results of this research show that the newly invented flexible railway is physically feasible.
