摘要
文章通过风洞试验方法研究不同方案裙板在无侧风和有侧风情况下,对国内某型高速动车组气动阻力及侧风稳定性的影响。研究表明,在无侧风和有侧风情况下,全包裙板方案减阻效果均为最优,无裙板方案最差,有侧风时各节车阻力系数分布发生明显变化;有侧风情况下,与对阻力系数影响相反,全包裙板方案侧风稳定性最差,无裙板方案最优。
The wind tunnel tests were carried out to study the influence of different skirt plates on the air-drag and cross wind stability of a certain domestic high-speed train under no crosswind and crosswind.The results showed that the air-drag reduction effect of all-in-skirt scheme is the best,and the no-skirt plate scheme is the worstin both cases,and the air-drag coefficient distribution of each car has a significant change;In the crosswind case,comparing with theinfluence of the air-drag coefficient,the no-skirt plate scheme is best,and the full skirt scheme has the worst side wind stability.
