Abstract The article presents an analysis of the methods for studying the dynamics of the branches of the track bypass, substantiates and proposes a research methodology and a simulation spatial model of the track mover of a cross-country transport vehicle, which differs from the common string inertialess and rod inertial models of the branches of the track mover by the ability to take into account a complex set of kinematic and force factors excited during the movement of the tracked vehicle in steady and transient motion modes. The model is developed in the “Universal Mechanism” software package, combines the main dependencies of the machine’s suspension system operation in various driving conditions and the dependencies of the interaction of the track links with each other, taking into account the radial, longitudinal and torsional rigidities during their interaction. The model allows for further development for the purpose of in-depth study and consideration of various factors acting in the design elements of the track mover, such as the features of the interaction of the support rollers with the links in the support branch of the track, the formation features of the moment of resistance to rotation and the turning moment depending on the type of the turning mechanism — stepped, differential hydrostatic. The efficiency of the model is assessed using the example of studying the phenomenon of “capture” of the track by the drive wheel when running over a typical unevenness of a sinusoidal profile. The substantiation of the technical solution option for the problem is given, installation of a free branch damper, and the results of determining the numerical parameters of its dynamic loading in relation to the object of study, a cross-country tracked transport vehicle. Thus, based on the results of the studies, the features of dynamic processes in the track mover were established, the main patterns of the formation process of transverse oscillations, their dependence on the design parameters of the bypass and various operational factors were revealed.
