| 摘 要： | 轮胎-路面侧向附着动力学数学模型用来描述侧向附着系数与车轮滑动率的关系.通过把侧向附着系数表述为车轮滑动率的函数及全面考虑各种基本参数,如路面状况、车速、侧偏角、法向载荷、车轮外倾角和车轮滑动率等对侧向附着系数的影响,对 Pacejka 的模型进行了根本的变革.从而能使它们适用于轿车各种制动工况的研究.和前人有关的数学模型相比较,新模型具有实际应用意义.

| Abstract: | Mathematical models of tire-lateral mad adhesion for use in mad vehicle dynamics studies are set up to express the relations of adhesion coefficients with slip ratio in lateral direction.The models of tire-lateral mad adhesion revolutionize the Pacejka's model in concept and therefore make it possible for applications in vehicle dynamics studies by the expression of lateral adhesion coefficient as a function of wheel slip ratio,instead of the wheel slip angle,taking into account in the mean time the influences of mad surface condition, vehicle velocity,vertical load,tire slip angle,and wheel camber angle. |
