Stable algorithm to simulate dynamic undercarriage loads of tracked vehicles

The loads acting on the undercarriage of a tracked vehicle are composed from multiple operation situations which result in dynamic loads. These loads are influenced by different variables and also combinations of these. Within this paper a method is described to simulate the loads acting on the undercarriage taking into consideration the multitude of critical combinations of influencing variables. Priority is given to the description of a calculation algorithm which allows to dynamically simulate how an excavator runs over an obstacle considering numerous parameters like obstacle height, running speed, track deformation and response behaviour of the overall system.
