Problem. Further modernization of combat vehicles, associated with the installation of additional equipment, requires the use of more powerful engines, which leads to increased loads on parts and components of the onboard gearbox. In modern conditions, the onboard gearbox of the T-64 tank works at the limit of its technical capabilities. To maintain the existing advantages and eliminate these shortcomings, the design of the onboard planetary gearbox needs to be upgraded. Goal. The goal is to increase the load capacity and as a consequence to increase the service life of the elements of the onboard gearbox by carrying out optimization of the onboard planetary gearbox. Methodology. Methods for calculating planetary mechanisms and methods for analyzing the strength of gears were used to build a mathematical model. When constructing the optimal design algorithm, the method of differential evolution was used. Results. The literature review of the existing methods of multicriteria optimization of planetary gears has been made. According to the developed method of optimization of the onboard gearbox, a study of the parameters of planetary gear for optimality according to the criteria of maximum load capacity and minimum dimensions has been made. Originality. An algorithm for optimal design using the method of differential evolution for optimization of planetary gearboxes has been developed. Practical value. The use of the received design of a planetary gear reduce loading on elements of a transmission of the T-64 tank, thus the overall dimensions and design features of an onboard gearbox remain. The proposed approach to optimization of planetary gears can be used in the design of modern models of planetary gearboxes.
