| 摘 要： | 利用多体动力学仿真软件ADAMS/Car, 建立了车辆的动力学模型、道路模型以及车-路耦合模型, 通过改变路面摩擦因数, 分别模拟了晴天、雨天、雪天和结冰条件下的路面状况, 进行了单移线和阶跃转向2种常见行驶工况的仿真试验, 得到了车辆的侧向位移、航向角以及轮胎的侧向反力的响应输出, 分析了研究恶劣天气路面条件对行车安全的影响。计算结果表明: 雪天路面摩擦因数为0.28时, 在单移线仿真工况下, 车速为50 km.h-1, 车辆侧向位移达到4.50 m, 车辆容易超出车道, 发生碰撞危险; 在阶跃转向仿真工况下, 车速为40 km.h-1, 车辆将失去控制。

| Abstract: | In order to research the influence of road condition on running safety in atrocious weather,vehicle dynamics model,road model and vehicle-road coupling model were set up by using multi-body dynamics software ADAMS/Car.By changing road friction coefficient,road conditions in sunny day,rain,snow and freezing weather were simulated.Two virtual tests of single lane change and step steering were carried out,and the response outputs of lateral displacement,course angle and lateral force of tires were obtained.Com... |
