Abstract: The development of a suspension system capable of ensuring the reliable functioning of other vehicle systems and providing comfortable conditions for the crew remains among the important modern problems in military vehicle design. Traditionally, the studies of the functioning of suspension systems are carried out based on a linear model of the relationship between deformation and restoring force of an elastic element, which does not account for numerous factors that arise during movement over rough terrain. Progress can be achieved via the development of an approximate analytical method for studying such systems, which allows one to evaluate the effect of the entire complex of suspension parameters on the dynamics and stability of oscillatory processes. In this work, analytical methods for studying oscillatory processes of systems with concentrated masses are considered, and the conditions for their realization are derived. The conditions for the manifestation of nonlinearities in oscillatory processes are established. The need to refine computational models of existing systems and create new models that realistically reflect their dynamic processes has been proven. These circumstances suggest the need to solve a scientific problem, which involves deriving analytical dependencies to evaluate the impact of nonlinear suspension characteristics on the dynamics of the hull and tracked contour of the tracked military vehicle (TMV). The goal is to predict resonance phenomena during operation over rough terrain. The calculated dependencies themselves, obtained based on a nonlinear mathematical model suitable for the dynamic process, can serve as the basis for solving an equally important problem: determining dynamic loads. Thus, it is possible to analyze the influence of the entire complex of suspension parameters of the TMV on the smoothness of the ride solely by analyzing the solution (exact or approximate) of a mathematical model adequate to the physical process.
