Abstract:

The purpose of this feasibility study was to determine whether an analytical model capable of calculating the dynamic motion and loads in the tracks and suspension of a tracked vehicle could be developed. Such a model could be used to evaluate causes of track vibration and associated energy dissipation. An analytical model for the dynamic analysis of tracked vehicles has been developed and a computer program incorporating the model has been written. The vehicle suspension and track geometry are variables specified in the input to this program. The analytical model provides details of the track motion using a time history solution. Dynamic track tension, which can be correlated with the energy dissipated in the track, is determined as a function of time for each track link. Damping in the trackpin rubber bushing interface may be varied in separate analyses to study the effects of damping on dynamic tension and resulting energy dissipation in the track. The analytical model was configured to represent the M113 Armored Personnel Carrier. Sample analyses of this configuration were completed and tabulated results appear to be reasonable.
