The suspension-type monorail (STM) is a new type of rail transit, currently developing rapidly in China. Due to its short construction duration and high terrain adaptability, STM can save large land resources. In particular, by supplementing the traffic systems in large and medium-sized cities, STM can contribute to green tourism projects. However, no systematic study is devoted to the STM transit system in China, and there is still a lack of relevant knowledge and exploration, especially for the special combination system monorail bridge. In view of the real STM bridge, namely a long-span (55 + 100 + 55)-m cable-stayed bridge in this paper, and by applying wind-vehicle-bridge coupling vibration theory, ANSYS finite element method software, and Universal Mechanism multi-body dynamics software, finite element models are established for the bridge and multi-body vehicle, respectively. Furthermore, a co-simulation method is adopted to analyze vehicle-bridge coupling vibrations and ride comfort quality. According to the results, the dynamic responses of the monorail bridge and vehicle are greatly affected by the variation in wind speed, and it is necessary to take measures to decrease system vibrations, thereby ensuring ride comfort quality for vehicle passengers.

悬挂式单轨（STM）是目前在我国发展迅速的一种新型轨道交通。STM建设工期短，地形适应性强，可节约大量土地资源。特别是，通过补充大中城市的交通系统，STM 可以为绿色旅游项目做出贡献。然而，国内对STM公交系统还没有系统的研究，还缺乏相关的知识和探索，尤其是对于特殊组合系统单轨桥。本文针对真实的STM桥梁，即一座大跨度（55+100+55）米斜拉桥，应用风-车-桥耦合振动理论、ANSYS有限元法软件和Universal机构多体动力学软件，分别为桥梁和多体车建立了有限元模型。此外，采用联合仿真方法分析车桥耦合振动和乘坐舒适性。结果表明，单轨桥和车辆的动力响应受风速变化的影响较大，需要采取措施降低系统振动，从而保证车辆乘客的乘坐舒适性。
