摘要
本文将高速公路路面凹陷变形假设为Ricker小波函数 ,将车辆简化为两自由度的振动系统 ,分析了由于路面凹陷变形引起的车辆振动水平。从而为研究车辆 -路面的动力相互作用问题提供了基础性成果 ,也为在高速公路的设计、施工和养护中的应用提供了有益的资料。
Pavement depression is a common pavement distress of free way.Supposing that the pavement depression is a Ricker wavelet function,and then the moving vehicle's vibration level induced by it can be obtained by simplifying the vehicle to a two DOF vibration system.The study conducted herein offers us some fundamental results for further recognition of vehicle_pavement dynamic interaction problems,as well as for the applications in the design,construction and maintenance of free way.
