摘　　要：通过模态截断方法对路基路面有限动力学模型进行降阶处理,并计算轮胎力与路面动变形之间的传递函数,把路面不平度输入模型作为激励,用Simulink对车辆与路基路面之间的耦合关系的传递函数模型进行仿真。分析得到了车速、路面等级、动态轮胎力和路面动变形等之间的关系,为下一步分析车辆与道路之间的相互作用提供重要依据。The finite dynamic model of roadbed-road surface is reduced order by the method of modal truncation, and calculated the transfer function between the tire forces and pavement deformation. With the input model of pavement roughness as the excitation, the transfer function model of the coupling relation between vehicle and road was simulated by the Simulink system. It showed the relation among the speed, road grade, dynamic tire force and pavement deformation, it provided an important basis for the further analysis of the interaction between the vehicle and the road.
