Parameters of the vehicle undercarriage affect the vehicle movement and its behaviour on the road or on the terrain. Basic geometry of the vehicle undercarriage can be expressed by mathematical methods, yet undercarriage analysis of the moving vehicle on the terrain is very complex procedure. We have to take into account wheels vertical movement and deflection (which influences the suspension system). Utilization of the simulating technologies can be very beneficial for solution of this issue. The paper is focus on mathematic model of the vehicle undercarriage and its application for analysis of the vehicle undercarriage.

The paper is focused on the analysis of tracked vehicle propulsion mechanism during a movement of the vehicle. Propulsion mechanisms of tracked vehicles are highly loaded by dynamics stress. This stress arises by vehicle movement on a terrain and by vibration of tracks. Analysis of this stress is essential in the process of development or optimization (modernization) of the vehicle. Simulating technology was chosen for analysis of selected vehicle, because analysis of propulsion mechanism stress of tracked vehicle is complex process. Utilization of simulating technologies enables extensive analysis of vehicle behaviour including analysis of stress of main parts of the vehicle.
