摘要/Abstract

摘要： 综合分析了降雨、超速情况下曲线路段小客车行车风险。利用Carsim软件建立车辆动力学仿真模型,以临界附着系数作为小客车行车风险评价指标,运用Matlab软件建立小客车行车风险评价模型并进行风险分析。结果表明：在设计速度80 km/h时,当行驶速度超过96 km/h,小客车在降雨的曲线路段行驶时发生侧滑的风险概率大于48.40 %;当降雨强度大于1.5 mm/min,小客车在曲线路段超速行驶时发生侧滑的风险概率大于16.35 %;在降雨、超速情况下,小客车在曲线半径为250 m的曲线路段行驶时发生侧滑的风险概率大于90 %。

Abstract: In consideration of rainfall and over-speeding, the risk of passenger car moving on curved sections was analyzed synthetically. The simulation model of the dynamic characteristic of passenger car was established using Carsim, the critical adhesion coefficient was used as the evaluation index of passenger car moving risk, and the evaluation model of passenger car moving on curved sections was established using Matlab. The results show that under the situation of design speed 80km/h, when driving speed exceeds 96km/h, the risk probability of passenger car moving on rainfall curved sections exceeds 48.40%; when the rainfall intensity is bigger than 1.5mm/min, the risk probability of passenger car over-speeding moving on curved sections exceeds 16.35%; under the situation of rainfall and over-speeding, the risk probability of passenger car moving on curved sections which radius is 250m is 100%.
