摘　　要：为了改善汽车的抗侧翻性能,建立了考虑悬架和轮胎侧向变形影响的一种改进的汽车侧翻模型,并基于该模型,提出了一种关于弹簧刚度和减振器阻尼的调整策略。通过对某一款SUV的仿真试验验证了该调整策略的有效性,同时还研究了前轮外倾角和前束角对侧翻倾向的影响。In order to improve the anti-rollover capability of vehicles, a refined vehicle rollover model is built, taking into account the effects of suspension and tire＇s lateral deformation. Based on the model, an adjusting method for spring stiffness and the damping of shock absorber is put forward, which is then validated through the simulation tests on a SUV. In addition, the effects of camber and toe-in angles of front wheels on rollover propensity are also studied.

关 键 词：侧翻 弹簧刚度 减振器阻尼 前轮定位参数
