Influence of Vehicle Parameters on the Dynamics of Pavement Structure due to Vehicle-Road Interaction
A three-dimensional vehicle-road interference system was established in this work. A moving vehicle was simplified to a quarter-vehicle model. An infinite plate on Kelvin foundation was employed to model the pavement system. Through integral transform, the timedependent displacement and stress of the pavement are obtained by linking together the characteristics of a road profile and a moving vehicle. The spatial and time change rules of the plates displacement and stress were presented to illustrate the analytic results derived from the established framework. A detailed model parametric study then followed to show the effect of vehicle velocity, suspension stiffness, suspension damping, tire stiffness, and tire damping on the road dynamic response. The conclusions obtained from this work may be useful for reasonable vehicle suspension design, which pays more attention to avoid the pavement premature failure and extend pavement life-span.
