MSC. ADAMS, a multibody dynamics software, is powerful in modelling of complex mechanical systems and realizes fine simulation on vehicle-pavement coupled system (VPCS). Existing MSC. ADAMS treats pavement as a rigid body and simplifies tyres as a group of mathematical formulas. Therefore, finite element model of tyre and road is the basis of flexible VPCS modelling. In this paper, finite element model of tyre and road was established and introduced into MSC. ADAMS through the MNF file. After the spatial position of finite element model was adjusted, a three-way force could be applied between tyre and road surface by setting their contact pattern. An elaborate VPCS model can be established by combining the universal vehicle prototype model and the established flexible road and tyre model based on MSC. ADAMS.
