摘要
现有的车辆与道路相互作用的研究只是考虑平直路面下路面不平整度引起的车辆动载荷分析,行驶工况对车辆动载荷的影响也很重要。针对车-路耦合作用的特点,运用ADAMS/Car动力学仿真软件,建立重型卡车的多自由度仿真模型和3D弯坡路面模型。重型卡车与弯坡路面耦合仿真模型的建立为更加精确地进行车辆-道路相互作用研究提供了可能。
In the vehicle and road interaction study, the analysis of dynamic load caused by the road roughness is important, but the driving conditions on vehicle dynamic load are also important. According to the process of coupling vibration between mad and vehicle, the models of heavy truck and 3D curved road were built with the ADAMS/Car dynamics simulation software. The creation of coupled simulation model provides reference for improving the precision of vehicle-road interaction.
