摘要
良好的横风运行安全性是实现高速动车组速度能力提升的有效手段。现搭建了基于空气动力学和车辆系统动力学的高速列车车辆横风运行安全性耦合计算模型,根据动车组在不同车速(150～300km/h)和风速(10～35m/s)下的气动力和气动力矩计算结果,分析了不同气动载荷对动车组动力学性能的影响。在此基础上,提出了CRH3G动车组的横风运行安全速度域。
Good running security under cross wind is an effective way to achieve high-speed capability for high speed EMU. This paper establishes the running security analysis model under cross wind based on aerodynamics and vehicle dynamics. Then aerodynamic loads including forces and torques at a different train speed （150-300 km/h） and wind speed （10-35 m/s） are calculated, and the affect on the dynamic performance of EMU is analyzed. On this basis, the security speed domain for CRH3G EMU is proposed at cross-wind running condition.
