This article discusses the application of the topological model method based on finite element modeling of one of the tracked vehicle transmission elements. The complex loading of the gear shift shaft is considered. In the process of work, a strength calculation of the transmission shaft was made and thematic optimization was carried out. The problem was solved according to the following principle: stiffness was taken as the objective function, and the mass of the part, which is 70% of the mass of the designed part, was taken as the constraint. On the basis of a topologically optimized model, the variants of the intermediate shaft of the gearbox were improved with subsequent strength calculations.
