ABSTRACT
To study the dynamic response of roads under non-stationary random excitation, a dynamic
differential equation is constructed firstly based on a two-axle half car model, and white noise
to simulate road roughness is then filtered. Finally, non-stationary responses of different
vehicle acceleration conditions are obtained. An infinite multi-layer plate on a viscoelastic
half-space foundation as a model of the road structure and an analytical solution for the
road dynamic response are obtained. Based on a numerical example, the dynamic response
of a four-layer road model under vehicle loads is discussed. The study fills the gap in the
theory of multi-wheel vehicle models.
