摘要
根据电动车组气动特性的试验研究结果,导出了液力传动动车组中动车受横风作用时所受到的气动升力、侧力和侧翻力矩,并对动车受横风作用时的直线运行性能进行了动力学分析。分析结果表明,迎风侧车轮减载是影响动车安全运行的重要因素,动车在常值侧风工况下运行速度不应超过140km/h,在阵风工况则应低速运行。
On the basis of the test and research results of the aerodynamic characteristics of EMU vehicles, the aerodynamic floating force, lateral force and rolling turnover torque are derived. The performance of power car on straight railway line is analyzed when it is acted by cross winds. Analytical results show that the wheel unloading on the windward wheel is an important factor for safe running of power car, the running speed of the power car should not exceed 140 km/h when it is acted by the constant cross wind, and should run slowly while by gusty wind.
