摘　　要：对导轨式胶轮智慧捷运系统(RRT)进行了车-桥耦合系统动力学仿真分析,研究了10 m10 t RRT系统在箱梁、U梁和钢-混梁3种轨道梁形式和6种跨度的组合工况下的动力响应分析,以期寻找车辆与轨道梁的最佳匹配关系。研究结果表明:RRT车辆通过3种轨道梁时,车辆与轨道梁的动力学指标均符合规范要求;车体横、垂向加速度及平稳性指标随跨度增大有小幅增大;10 m10 t RRT系统的最佳匹配方案为35 m跨度的箱梁或U梁。本文研究成果可为RRT系统的动力分析提供指导和借鉴。In this paper, the dynamic simulation analysis of the vehicle-bridge coupling system of rail-guided rubber-tyre rapid transit(RRT) is carried out, and the dynamic response analysis of the 10 m10 t RRT system under the combined working conditions of box girder, U girder and steel-concrete girder and six spans is studied, so as to find the best matching relationship between the vehicle and the rail girder. The results show that when the RRT vehicle passes through the three kinds of rail girder, the dynamic indexes of the vehicle and the rail girder meet the specification requirements;the lateral and vertical acceleration and Sperling indexes of the car body increase slightly with the increase of the span;the best matching scheme of 10 m10 t RRT system is 35 m span box girder or U girder. The research results of this paper can provide guidance and reference for the dynamic analysis of RRT system.
