Modeling and Simulation of Multibody Dynamics for Tracked Vehicle Based on RecurDyn

A dynamics model of the tracked vehicle was constructed based on RecurDyn, an analysis software of multibody dynamics. The modeling principle of the road was introduced, and the road models were constructed. Then the dynamic analysis of the tracked vehicle under the actual conditions was introduced. Simulations of the tracked vehicle on the hard road and the dry sand road were implemented respectively. The results of the simulations were analyzed and discussed. Mechanics performances of the important parts of the tracked vehicle was obtained, which provided a real external condition to the analysis of the planetary gear train.
