摘要
在分析行车荷载作用下路面解耦分析法缺点的基础上,提出耦合分析法.并借助有限元软件ANSYS/LS-DYNA,建立了车-路耦合动力学模型,分析了移动荷载作用下沥青路面的动态力学响应.计算结果为确定压电俘能系统的结构及埋设深度提供了依据.
Based on the analysis of the disadvantages of the decoupling analysis method applied to pavement loaded with moving vehicles, the coupling analysis method is put forward.Using the finite element software ANSYS/LS-DYNA, the dynamic mechanical coupling model is built between vehicles and pavement.The dynamic response of pavement under moving vehicle load is studied. The results of numerical simulation offer a reference for the structure design and embedding depth of the piezoelectric energy harvesting system.
