摘　　要：为提高大型客车在弯道路段的行驶安全性,在现行的道路平曲线半径计算模型基础上,提出平曲线处大型客车最大安全运行速度计算模型。通过选取大型客车为研究对象,首先对其前后轴内外轮的受力进行了分析,确定了客车最易发生侧滑的车轮,并综合考虑车辆结构与动力学特性、道路平曲线以及路-轮胎-车耦合等因素,应用系统动力学理论,构建了公路平曲线段处客车发生侧滑时的最大安全行驶速度计算模型。然后利用该模型计算了不同道路条件下的平曲线段处大型客车最大运行速度。In order to improve the safety of coach driving on curved road,we proposed the maximum safe driving speed calculation model of coach on horizontal curved road based on the current horizontal curve radius calculation model. The coach is selected as the research object. First,the forces of inside and outside wheels of front and rear axles are analyzed to identify the wheel that most likely to happen sideslip. Based on comprehensive consideration of the vehicle structure and dynamics characteristics,road horizontal curve,and road-tire-vehicle coupling factors,the calculation model of the maximum safe driving speed of coach on highway horizontal curve is constructed. Then,the model is used to calculate the coach＇s maximum speeds on curved road under different road conditions.
