Dynamic Modeling and Experiment of Military Tracked Vehicle

In this paper, the nonlinear dynamic modeling methods for the virtual design of tracked vehicle are investigated by using multibody dynamic simulation techniques. This research focuses on a heavy military tracked vehicle which has sophisticated suspension and rubber bushed track systems. Each track link is modeled as a body which has six degrees of freedom, and two compliant bushing elements is used to connect track links. In order to validate the developed nonlinear multibody dynamic model against the experimental measurements, several empirical techniques are applied to the physical proving ground tests of the high mobility tracked vehicle. In this empirical validations, positions, velocities, accelerations and forces of the chassis and the track sub-systems are correlated accordingly.
