跨座式城市单轨交通车辆直线段运行时，横向风的作用将会严重影响运行的平稳性乃至安全性能。由此，首先对车辆行驶过程中的横向风作用载荷进行分析，运用ADAMS多体动力学仿真软件建立跨座式单轨车辆“车体—轮胎—轨道梁”耦合系统动力学模型，分别对不同横向风速及不同车速时车辆直线段运行平稳性进行仿真分析。仿真结果表明：在横向风条件下，车速和风速的变化对的跨座式单轨车辆横向加速度影响较大，并进一步影响车辆的运行平稳性。且当车速或风速过大时，车辆会发生失稳现象。分析的结论对于这种车辆的设计可提供一种警示作用。

When the straddle-type monorail vehicles are traveling in a straight track section, lateral wind will seriously de-teriorate the riding stability and safety of the vehicles. In this article, the lateral wind load for the traveling vehicle was ana-lyzed. The“car body-tire-track beam”coupled system model for straddle-type monorail vehicles was established by means of the multi-body dynamics analysis software ADAMS. Then, the riding stability of the vehicle was simulated under the condition of different wind speeds and different vehicle speeds. The results show that variations of wind speed and vehicle speed have large influence on the lateral acceleration of the vehicle, so they also have large influence on the riding stability of the vehicle. When the wind speed or vehicle speed exceed their critical values, the vehicle will lose its riding stability. This conclusion has provided a warning for the design of straddle type monorail vehicles.
