This research focuses its attention on the riding stability of straddle-type monorail vehicles under the lateral wind condition by means of the multi-body dynamics analysis software Adams to set up a "car body-tire-track beam" coupled system model for the straddle-type monorail vehicle. Then, based on the principles of aerodynamics and considering that the wind pressure center changes as a result of the movement of the vehicle, calculation and contrastive analysis of the riding stability of straddle-type monorail vehicle under various car speeds, wind speeds and track shapes are performed through simulation. Finally, the conclusion is arrived at that changes of car speed and wind speed can exert a great influence on the transverse acceleration of straddle-type monorail vehicles affected by lateral wind, and an excessive speed of vehicle or wind may result in imbalance of the vehicle, which can possibly act as a reference for further exploring the crosswise riding stability and safety of straddle-type monorail vehicle under lateral wind.
