Abstract: A three-dimensional heavy vehicle-pavement-foundation coupled system is modelled as a seven DOF vehicle moving along a simply supported double-layer rectangular thin plate on a linear viscoelastic foundation. Using the Galerkin method and a quick direct integral method, the dynamic responses of the coupled system with stochastic road surface roughness are obtained numerically. The effects of vehicle and road parameters on vehicle riding comfort and road damage are also investigated and some interesting conclusions are found which are beneficial to parameter design. In addition, the validity of simulation results is verified by a field test.

Keywords: vehicle-road interaction; parameter design; low dynamical design; double-layer thin plates; viscoelastic foundation; dynamic response; heavy vehicles; road surface roughness; ride comfort; road damage; simulation.
