The coupling effect of ground, track and wheels of track vehicles was studied. The external factors influencing the dynamic characteristics of the track vehicles were analyzed. Taking a real track-vehicle as an example, the simulation model for dynamic performance analysis was established by means of ATV software. The dynamic characteristics of the track vehicle were studied under the condition of different ground topography, vehicle speed and initial track’s tension. This work has provided a basis for track-vehicle design and optimization.
