The paper describes the developed dynamic model of the caterpiller’s power transmission. Its advantage is the integrated dimensional model of caterpillar propeller. Animated motion modeling provides the formation and transfer of kinematic and dynamic disturbances from caterpillar chassis, causing the greatest loadings of the power circuit sections. The principle of power transmission mathematical model’s differential equations forming is described. result of the model’s computational research is a set oscillograms of the drive wheel’s torque changing for different operating modes. The values of power transmission masses’ natural frequencies are obtained. The research of the nature of transmission sections’ dynamic loading by torsional vibrations, that arise and spread on the shafting, when the linked track rewinds, is carried out.
