An important issue, which should be taken into account while analyzing the dynamics of vehicles moving along an uneven road surface, is the proper representation of its real shape. Two mathematical models of the road surface - continuous and discrete were considered in the method presented in this paper. These models were used in the computer simulations of dynamics of a special vehicle with a high gravity centre, which moved along an uneven road surface. The simulations were carried out using the worked out program package, in which four main modules could be differentiated such as: preprocessor, solver, postprocessor and 3D animation. This package was implemented combined with the Blender graphics environment – in authors’ opinion it is an innovative approach. Owing to this models of uneven road surface (theoretically of any shapes) can be built and they are input data for both the solver and animation modules. Additionally, the Blender tool can be used to prepare 3D objects, which are used in the animation process of the moving model of a vehicle. According to the authors', developed program package developed on the basis of the mathematical models for the analyzed vehicle and road surface can be interesting for engineers designing special vehicles. By performing different types of the computer simulations, the engineers can improve the vehicle being built and reduce cost of its road test.
