Abstract

The gear assembly of the rotational motion drive of the spacecraft system is considered. Such gear assemblies are one of the main elements of spacecraft systems with the use of large-sized structures that are folded in the transport position. Due to the development of computer technology, it becomes possible to create more accurate simulation models of such structures. The aim of the work is to create a simulation model that allows to analyze emerging loads on a wave transmission, which is part of the gear assembly of the spacecraft drive. Section one discusses the process of creating a finite element model of the drive. One of the features of creating a finite element model is a method of taking into account the preliminary stress-strain state in the structural elements of the wave transmission. Section two analyzes the data obtained during the calculation. The obtained equivalent stresses on the structural parts, contact stresses in the gear engagement are investigated, the torsional rigidity of the gearbox elements is determined, various tooth positions are considered during movement. The influence of loads applied to the output link of the gearbox on the surface of the gears is investigated. The obtained simulation model allows us to consider similar gear assemblies in which wave transmissions are used.
