The paper describes possible design of vehicle track computation model and basic testing step of dynamic loading simulation of the track. The computational model is built for computational simulating system MSC. ADAMS, Tracked Vehicle Toolkit. Computational model intended for MSC computational system is built from two basic parts. They are geometrical and contact computational parts of model. Geometrical computational model consists of basic parts of vehicle undercarriage movable parts. Contact computational model consists of impact and frictional forces system. The aim of the simulating calculation is the determination of change influence of specific vehicle track constructive parameters (curve track geometry or track preloading) on changes of examined qualities of the vehicle track link (reaction force against motion, minimal track link speed and medium track speed). The results of simulating calculations are given by using of afore-mentioned model. The full model consists of all parts of real vehicle undercarriage design. The computing result sample comes out as one of many possible cases. The influence of changes of driving sprocket diameter values on the needed torque changes of driving sprocket is displayed in the article. Further research plans are described in the article as well.
