Abstract: For the complex problems of ground-track-wheels coupling system excitation characteristics, a dynamics model of the tracked vehicle suspension system was established leaving out the track impacts. The theoretical calculations of the road wheels dynamic displacement were realized through kinetic equation. It was then simulated under various working conditions. A multi-body dynamics simulation model was proposed. Comparing the simulation result with that of the theoretical calculations, the change regulation of the road wheels dynamic displacement with the vehicle speed was analyzed. The results provide a theoretical reference for designing and developing the tracked vehicle. A technical support for loading excitation directly on road wheels about vehicle road simulation system is provided as well.
