摘　　要：高跨立体有轨电车是一种新型的轨道交通车辆,它运行在小汽车之上、高架桥和立交之下的道路空间,车体下部可让小汽车通行。给出了高跨立体有轨电车的一种实现方案:走行部采用独立车轮轮座结构,车体支撑在4个向内倾斜的走行部之上,车体的重心远低于空气弹簧的支撑面高度,形成被动摆结构;在走行部和车体之间设置横向拉杆以增加了结构的抗侧倾性能。建立了高跨立体有轨电车的动力学模型,仿真分析了立体有轨电车的曲线通过性能和运行平稳性。仿真结果表明:高跨立体有轨电车具有良好的曲线通过性和运行平稳性,其结构设计方案可行。Straddling tram is a new urban rail transit vehicle which runs on road space between groung cars and elevated bridges,or under the interchange, so cars can run under the straddling tram line. In the paper, a scheme of straddling tram made up of an elevated carbody is presented, which has 4 tilting inward running gears with independently rotating wheels and lateral rods. The carbody is located on the air springs of running gear, the height of mass center of carbody is far below the air springs,thus the passive pendulum is formed. The lateral rods that connect carbody and running gears will increase the sway stability. The dynamics model of straddling tram are established for evaluating the dynamic performance. The simulation results show that the straddling tram has a good performance on the curving and good riding quality, so the dynamics feasibility of straddling tram is preliminarily verified.
