Road Dynamic Responses Under Moving Vehicle Loads Based on Three-Dimensional Finite Element Model
In this chapter, based on the layered plate theory, a 3-D finite element model of the road system is established by ANSYS10.0 software. The time-dependent deflection, stress and strain of the road are obtained by linking together the road surface roughness, a moving heavy duty vehicle, and a multi-layered road system. The road fatigue life is calculated by taking the tensile strain at the bottom of the asphalt surface as the evaluation index. A parametric investigation then is conducted to show the effects of vehicle load, road grade, vehicle moving speed and vehicle parameters on the road fatigue life. The fatigue-induced failure regularity and mechanism of the road system under a moving stochastic load is elucidated.
