Abstract


The article contains a brief overview of the results of studies of elastic interaction of a caterpillar with a variety of soils and types of irregularities, forming a dynamic loading mover. The conclusion about the need to consider the periodic changes in the rigidity of the elastic interaction of tire road wheels with rubberized running track, which may lead to the appearance of parametric resonance. Based on the theory of nonlinear interaction of elastic elements are determined by the region of stability of parametric oscillations is determined by the minimum value of the modulation depth hardness of the elastic interaction, providing an exception parametric resonances at high speeds. The experimental validation of the developed mathematical model of the machine when driving on paved roads confirms the hypothesis of limited longevity of elements of caterpillar tracks. In accordance with the results of the study suggested embodiment of the caterpillars, which provides an exception parametric resonance. It shows the results of evaluating the effectiveness of the study.
