Prediction of Vibration in Bandtrack-Driven Military Vehicles

Analytical methods for predicting the vibration levels in bandtrack-driven military tracked vehicles are described, contrasted, and compared. These methods range from parametric models superimposed upon existing dynamic simulation models to first principle models developed from direct measurement of suspension and band-track geometric physical properties. The first principle models are implemented in a multibody dynamics computer code for mechanical system simulation and used for predicting vibration, track retention, and rolling resistance.
