Abstract

A mathematical model of a heavy-duty track modular unit, in which the mechanical suspension damper is a topologically optimized elastic frame with superelastic reinforcing elements made of a composite material with thermoelastic martensitic transformations, is proposed. The model is used to evaluate the internal force factors arising at the points of contact between the track rollers and the support platform. The model allows taking into account the influence of the dynamic load from the inertia of the nodes and parts of the mechanism. This model can be used to analyze the impact of the failure of the track rollers of tracked vehicles on the redistribution of forces between the remaining serviceable rollers. Based on the results of loading simulation, dependencies are obtained that make it possible to judge the level of loading of the support wheels in two operation modes; recommendations are given for further refinement of the model.
