Abstract

Abstract: While a vehicle running on the road,the vibration of vehicle is coupled and interacted with the road.The vehicle is simplified into a two DOF vibration system and the road is dispersed to the multi-layer FEM systems.Viewing the road and vehicle as a whole system,each of them is a subsystem of the whole system.Then a model of vehicle-road vertical coupled system is established and the dynamic equilibrium equation of vehicle-road systems are deduced.It provides reference to the further research about interaction and dynamic characters of vehicle-road on highway.

Key words: vehicle, road, vertical coupled, road roughness, dynamic analysis

摘要： 车辆在道路行驶过程中,车辆的振动与道路是相互作用和相互耦合的。把车辆简化为两自由度振动体系,将道路离散为多层体系的有限元模型,将车辆、道路视为一个整体的系统,车辆和道路分别是整个系统的一个子系统,建立了车辆-道路垂向耦合动力分析模型,推导出了车辆-道路系统的动力平衡方程组,以期为高速公路车辆与路基动力相互作用的进一步深入研究提供参考。
