Power loss analysis of tracked travelling unit of high-speed tracked vehicle

For the problem of large power loss and low efficiency of tracked travelling unit of high-speed tracked vehicle, each part of power loss is first analyzed in theoretically. Then simulation analysis is done with the help of multi-body dynamics software RecurDyn and Matlab, from which we get the proportion of each part of power loss. The results show that the sprocket loss and impact loss make up the vast majority of the total power loss when driving at a high speed. The conclusion of this paper can provide theoretical basis for improving the efficiency of high-speed tracked vehicle, besides, it can also contribute to an effective way of improving the efficiency of tracked travelling unit.
