The paper presents the problem of modelling dynamics of motor vehicles in the convention of multi-segment systems. The assumptions used in modelling process arepresented and the characteristics of elastic - damping elements of tracked vehicle suspension system are determined. This paper presents the identified mass and the geometrical parameters of the vehicle, on the basis of these parameters in Virtual.Lab software environment the simulation model was developed. The model describes the elements of a tank that does not change their position relative to the reference coordinate system, they are: the turret, muzzle, body case, and other components such as: wheels, torsion shafts, damper levers and links. The tank tracks are omitted in the simulation model. The results of numerical simulations in the form of displacement courses of characteristic points of the hull and displacements of the wheels axles in an assumed reference coordinate system are also included. The simulation results were compared with experimental results obtained on the proving ground. The results of experimental measurements carried out on the tank range, were used to precise tune a mathematical model of the vehicle. The results of numerical simulations confirmed validity ofthe assumptions in the modelling process, since good agreement was obtained with results from experimental investigations. The developed models will be used to optimize the characteristics of vehicle suspension.
