摘要
考虑车辆在侧风条件下运行时所受到的侧向力、升力、侧滚力矩、点头力矩、摇头力矩五种侧风载荷,并基于多体动力学仿真计算软件Simpack,介绍了考虑侧风作用的车辆动力学仿真计算方法。通过此方法,分析了侧风载荷随着环境风速和车辆运行速度变化而变化的规律,以及某动车组车辆在侧风工况下通过曲线线路时的安全性指标的变化规律。
In this paper five kinds of crosswind load such as lateral force, lift force, rolling moment, nodding moment and yaw moment have been considered when the vehicle is running under the crosswind. And the simulation and calculation method of vehicle system dynamics under the crosswind is presented based on the SIMPACK which is a multibody dynamics simulation software. The variation of crosswind load with the crosswind speed and the vehicle speed is analyzed by the method. The variation law of safety index of a EMUs vehicle under the crosswind on a curve line has also been discussed.
