摘要

针对路面结构响应动力学理论模型构造实验模型。经模型试验与数值仿真相结合方法研究移动荷载下路面动力学响应。设计含车辆模型及分布刚度路面模型的车路模型试验系统，其中车辆模型包括谐振源车辆模型及1/4车模型。利用模型试验与数值仿真方法分别对移动简谐激励及冲击激励作用的分布刚度路面动力响应进行研究。数值仿真与试验结果对比表明设计的模型及实验方法可近似模拟车-路耦合作用及路面动力响应。

Abstract

In order to compare with dynamic response theoretical model of pavement, a new test rig is proposed in this paper. With help of experimental and numerical simulation methods, the dynamic response of pavement under moving load is researched. The vehicle-pavement test rig includes a vehicle model and a distribution of stiffness pavement-roadbed model, and the vehicle model includes a resonance source vehicle and a quarter vehicle model. The dynamic response of distribution of stiffness pavement under moving resonance load and fixed shock excitement were studied respectively by using experimental and numerical methods. The analysis results shows that the designed test rig is usable, and the experiment results can meet closely with numerical results.
