To ensure the constantly increasing requirements for the comfort of transport vehicles, primarily characterized by the level of vibroacoustic radiation, modern methods of NVH optimization of transmission parameters are used. Progress in the development of software systems makes it possible to investigate the disturbances arising from the manifestation of nonlinear properties of dynamic systems, as well as to make reasonable improvements and changes at the early stages of design. The presented work is part of the current research on the creation of a verified mathematical model of a promising automatic transmission (AT), which should adequately describe its vibroacoustic behavior during operation, and its purpose is to create a digital copy of a promising AT for a road truck of category N2 and optimization of the gear wheels included in it. The paper describes the processes of creating a digital copy of a promising automatic transmission in the Simcenter 3D Motion Trasmission Builder software and optimizing gears in the KISSsoft software, as well as the results of determining the optimal parameters of gears. The novelty of the research lies in the creation of a digital copy of a promising automatic transmission, which makes it possible to simulate any mode of operation to obtain the loads necessary to determine the vibroacoustic behavior of the transmission. In accordance with the purpose of the work, a digital copy of a promising automatic trans-mission of a truck was created to determine the loads in the supports. As a result of the calculated studies, the optimal parameters of the gears were obtained according to the criterion of minimizing the transmission error (TE). The results of the study made it possible to clarify the algorithm for determining and optimizing the loads formed in the gearing and transmitted to the transmission case, which can later be used in the design of gearboxes and gear units of transport machines.References
