It provided a basis for building more accurate dynamical model. 4. Based on AD250 articulated dump truck multi-rigid body dynamics model, flexiblemulti-body models of suspension components for which the deformations are relatively important were built using finite element method. Modified Craig–Bampton modal synthesis and flexible multi-body methods were applied to build rigid-flexible coupling multi-body model of the truck. Dynamic simulations with different road profiles were performed.
