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。

Geometrical and physical parameters of components of the absorber in the virtual prototype follow from those technical data of a specific passenger car.

The piecewise, the hysteretic looped and the abnormal looped hysteretic force-velocity curves for the absorbers are, respectively, input into the prototype.

减振器阻尼力—速度特性是根据MTS减振器特性试验机试验结果，通过分段拟合，分别以分段线性、迟滞环和迟滞环畸变情况输入虚拟样机进行仿真分析，试验及仿真结果比较说明：减振器速度外特性采用迟滞环非线性，比采用双线性化模型更接近试验结果，能够更合理地解释试验现象；减振器阻尼力速度特性曲线出现畸变，如在复原行程初期迟滞特性曲线出现交叉现象，可以引发减振器系统动力特性的高频振动成分增加。
