Abstract
Relevance Devices and apparatuses operating in outer space have a high cost due to extreme operating conditions and high requirements for reliability, which, as a result, leads to the need for thorough testing of the performance of all elements, assemblies and subsystems before being sent into space underground conditions. Among the many elements of spacecraft, the process of testing transformable parts that deploy in space from the transport position to the working position is difficult, however, under terrestrial conditions, due to the influence of the weight of the elements on the deployment system and hinges, testing without auxiliary systems does not guarantee reliability of the conducted experiments. Accordingly, one of the solutions is the use of weightless systems that compensate for the weight of the transformable parts of spacecraft. Aim of research Analysis of the operation of a support weightless system based on a mobile robotic platform on holonomic wheels using mathematical and natural modeling. Research methods Mathematical and natural modeling. To compare transient processes, the main quality indicators used in the theory of automatic control are used. Results The transient responses are obtained for the angles of deflection and the angle of deflection of the operation of the model and the full-scale stand of weightless systems. Qualitative and quantitative analysis confirms the efficiency of the method and the closeness of the obtained natural results with the model ones. The weighing accuracy obtained on a full-scale stand is 97.7 %.
