摘　　要：研究了不同横风风速下,列车在通过曲线道路时空气动力性能并进行仿真分析。根据计算得到的数据,分析了不同横风速度时相应的车体纵、横向气动力变化和列车的倾覆系数。参照有关高速列车曲线通过稳定性评定标准,给出了9级横风风速下单轨列车安全运行的速度限值,为今后单轨列车在横风作用下的运行安全性提供一定的依据。Monorail train aerodynamic performance of train through the curve road under different cross-wind conditions was studied and simulation.According to the calculation data,the vehicle body longitudinal,laterally force variation and the train overturning coefficient under the different cross-wind conditions were analyzed.Reference to the relevant assessment criteria for the curve negotiation stability of high-speed trains running,the train speed limit for safe running under the cross-wind velocity 9 was obtained,which provided a basis for security of monorail running under cross-wind effects.
