采用CFD仿真分析的方法研究不同编组列车气动性能变化规律,仿真结果表明:在不考虑受电弓影响的情况下,列车编组与整车的气动力成近似线性关系变化,其线性规律与侧风状态无关。
採用CFD倣真分析的方法研究不同編組列車氣動性能變化規律,倣真結果錶明:在不攷慮受電弓影響的情況下,列車編組與整車的氣動力成近似線性關繫變化,其線性規律與側風狀態無關。

The CFD simulation analysis method was used to study on variation of aerodynamic characteristics for different marshalling trains. The simulation results show that: without considering the impact of pantograph, train marshalling units and aerodynamic forces are showing an approximate linear relationship, which has nothing to do with the side wind conditions.
