The results show that side force, lift and overturning moment obtained by simulation and by wind tunnel test are consistent. When train travels with certain speed, the aerodynamic force and overturning moment acting on passenger car running on bridge, embankment and flat will increase greatly as cross-wind becomes larger while those increase less when the train runs on cut. Under the condition of strong cross-wind, aerodynamic force and overturning moment acting on train traveling on bridge are the largest. So the train traveling on bridge tends to overturn compared with that traveling on other three kinds of railway conditions. Aerodynamic force and moment acting on train traveling on cut are the least.

研究结果表明：侧向力、升力和倾覆力矩数值模拟结果与风洞实验结果均吻合较好；车速一定时，随着侧风速度的增大，列车在桥梁、路堤、平地上运行所受气动力和倾覆力矩均急剧增加，而在路堑上运行所受气动力及力矩增加缓慢；当侧风速度一定的情况下，客车在高桥上运行所受到的气动力及力矩最大，因此，强侧风下列车在高桥上运行较容易发生倾覆事故；在路堑上所受到的气动力相对最小。

Using the models, the author has also calculated the vibration response to high speed railway vehicles of three types travelling over simply-supported beam bridges with various span lengths respectively. Based on the analysis of the computation results, the concept of resonance velocity of a bridge under a high speed running vehicle is present, and it is pointed out that comparatively great vibration of bridges on high speed railways is caused by bridge resonance resulted from the static force pulsating. In a vehiclebridge coupling vibration system, the damping constant of the axle spring is the main factor affecting the response variable of bridge velocity resonance, and the influence of track irregularity on bridge vibration on high speed railways is rather smaller.
