- Opis:
- 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.
