Abstract
The paper reported a full-vehicle simulation to investigate the dynamic attribution of pavement unevenness during the vehicle-road dynamic interaction process by full-vehicle model simulation. Artificial road profiles generated by the inverse Fourier transform (iFFT) approach in Matlab were imported to CarSim/TruckSim by Simulink. Three full vehicle models of a car, bus, and truck were simulated under five constant operation speed. The effects of roughness level and operation speed on acceleration and dynamic tire loading have been analyzed. This paper showed how the riding comfort and dynamic loading coefficient change over the pavement surface degradation, which could be used to assess and maintaining the road pavement.
