The results show that, for the first with no headwall, when there is no crosswind, it has small front face areas, so the aerodynamic resistance is the least. Since the second and the third have headwall, the front face areas are large, so they have bigger aerodynamic resistance. Under the condition of crosswind, as the third design option has the highest side beam, the area of positive pressure at the upwind is bigger, and the area of negative pressure is smaller when the bigger eddy area appears, so the side forces become larger. The first has the least side forces; the overturning moment of the first is the least.

研究结果表明：在无横风情况下，方案一中没有端墙，迎风面积较小，受到的气动阻力最小，方案二和三中平车有端墙，迎风面积较大，受到的气动阻力也较大；有横风情况下，方案三中平车侧梁较高，车体迎风面正压区较大，而背风侧产生较大的涡流区，在此区域内压力较小，故其横向力较大，方案一中平车侧梁没有加高，受到的横向力最小；方案一中平车倾覆力矩最小，稳定性最好。
