摘要
文章将车辆、道路作为整体系统的两个部分,把车辆简化为四自由度的1/2车辆模型,将道路离散为弹性多层体系的有限元模型,通过建立车辆道路耦合动力分析模型,推导出了系统的动力平衡方程组,并探讨了方程组的解耦方法,提出了反映车辆运行品质和道路设计参数的理论计算指标,为车路耦合动力分析的进一步研究提供了参考。
The article divides the vehicle and road into two parts,which simplifies the vehicles into a four DOF vibration system disperses the road to the multi-layer FEM systems.Through the establishment of the vehicle-road coupled system model, the dynamic equilibrium equation of vehicle-road systems are deduced, the decoupling method of the equations is explored,and the parameters of the theoretical calculation for the quality of vehicle and road design are proposed.It provides reference to the further research about the vehicle-road coupled dynamic analysis.
