为了研究铁道车辆的抗横风安全性,建立了整车模型并编制了计算程序。利用实车试验和风洞试验验证了模型的正确性。计算结果表明,半车模型代表了摇头运动对车辆倾覆影响的最恶劣条件。本文所提出的方法可以用于研究强横风造成车辆倾覆事故的原因分析,也可用于对特定风载情况下的车辆特性进行分析。
In order to study the anti-crosswind safety of railway vehicles, a complete vehicle model was established and a calculation program was compiled. The actual vehicle model and the wind tunnel test are used to verify the correctness of the model. The calculation results show that the half-car model represents the worst condition that the shaking motion affects the vehicle overturning. The method proposed in this paper can be used to analyze the causes of vehicle overturning caused by strong winds and to analyze the characteristics of vehicles under certain wind loads.
