The article presents the formulation and solution of the problem of optimization of the internal damping rubber elements of the roller wheel of tracked system. The optimal design search is based on the results of calculating the stress-strain state of the rubber element caused by the assembly of the roller and operational loads. As an objective function, the specific energy of deformation of the rubber was chosen. The geometric parameters of the rubber element of the roller wheel in the initial state and after installation in the structure are taken as variable parameters. Explicit and functional constraints in the form of inequations are imposed on the variable parameters. As a result of solving the optimal design problem, the shape and design parameters of the internal damping rubber elements of the track roller of the tracked system were obtained, which made it possible to reduce the specific strain energy during radial loading by 1.85 times
