【摘要】 高速公路已成为当前国内的重要出行方式选择,车辆行车的安全性与舒适性也越来越受到社会的广泛关注。利用车辆动力学分析软件,选取雅康高速公路第C3—C14合同段进行建模分析。该模型主要模拟在3种不同天气环境状态下的路面摩擦系数,并进行比较,给出车辆在不同路面环境下的建议行驶速度,以此验证该路线的设计合理性。仿真结果表明:在干燥及雨天路面环境下,车辆的建议行驶速度为100 km/h以内,该速度能使车辆的横向加速度保持在1.83 m/s~2以下;在冰雪路面环境下,当车速超过85 km/h时,车辆容易发生侧滑,行车速度建议在80 km/h以内。更多还原

【Abstract】 Expressway plays an important role in going-out in China. The safety and comfort of vehicle driving have drawn more and more attention from the public. This paper, using vehicle dynamics analysis software, selects the C3—C14 contract section of Yakang Expressway as modeling analysis. The model mainly simulates the comparison of road friction coefficients under three different weather conditions in order to verify the rationality of this route designed. The simulation result shows that under the conditions of dry road and rainy road, the recommended driving speed of vehicle is less than 100 km/h, and the lateral acceleration of the vehicle can be kept below 1.83 m/s~2. When the speed is more than 85 km/h on ice covered roads, the vehicle will be prone to sideslip. Thus the driving speed shall be recommended to be within 80 km/h.更多还原
