摘要
为更加准确地求解汽车静态最大侧倾稳定角,建立了综合考虑悬架组合角刚度和轮胎垂直刚度的汽车静态侧翻模型。应用该模型,对某型号客车的静态最大侧倾稳定角进行了计算,将求解结果和其他侧翻模型以及试验数据对比,结果表明该模型计算结果和试验数据很接近。利用该模型,还进行了侧倾稳定角主要影响因素的敏感度分析。
In order to calculate the maximum static stable roll angle accurately, it presentes a new vehicle static rollover model, which consideres the composite roll stiffness of the suspension system and the perpendicular stiffness of the tires. Then the maximum static stable roll angle of a certain bus is calculated with this model. The result shows that the calculated roll angle is close to that of the test. At last the sensitivity of the main influence factors of the stable roll angle is analyzed.
