Abstract
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.
How Multibody Dynamics Simulation Technology is Used
RecurDyn is used to model and simulate a rear-propelled track vehicle. This simulation was able to identify the relative importance of several power loss mechanisms and graph these loss mechanisms over time. Sprocket loss and impact loss make up the majority at high velocities. With this information, design improvements can be made that focus on sprocket loss and impact loss.
