Track Tension Analysis of Four-Wheel Drive Tracked Vehicles

The distribution of track tension on track link is complex when the tracked vehicles run at a high speed. A multi-drive track link structure, which changes the traditional induction wheel into the driving wheel was proposed. The mathematical model of the system was established and the distribution of track tension was studied. The combined simulation model of RecurDyn and Simulink of the structure with multi-drive track was established. The simulation results show that our proposed structure has more uniform tension distribution than traditional structures, especially under the high speed condition. The maximum tension can be reduced by 28 kN-36 kN and the transmission efficiency can be improved by 10%-16% under high speed condition with this new structure.
