Abstract

Abstract: In the vehicle and road interaction study,it is not enough to consider the influence of road roughness only on dynamic load,but the driving condition should also be taken into account.According to the vehicle-road coupling characteristics, the models of heavy truck and 3D curved road were built with the ADAMS /Car dynamics simulation software.Meanwhile, the dynamic loads between the wheels and the pavement on curved ramp road and straight road were analyzed comparatively． The result indicated that the pavement damage of curved road was larger than that of straight road

Key words: road roughness, curved ramp road, dynamic load, coupling vibration

摘要： 车辆与道路相互作用的研究不仅只考虑路面不平整度对车辆动载荷的影响，而且应考虑行驶工况对车辆动荷载的影响。针对车－路耦合作用的特点，运用ADAMS/Car动力学仿真软件，建立了重型卡车的多自由度仿真模型和3D弯坡路面模型，通过分析弯坡路面和平直路面下车辆对路面的动载荷作用。表明，弯坡路面的疲劳破坏程度比平直路面的大。
