An overview of modern tools for computer-aided design of technical systems is given. Using the method of comparing systems by the criterion of functional completeness, their main functionality, compliance with standards, and additional specialized applications are analyzed. It is shown how much computer-aided design systems accepted for comparison have differences or similarities in terms of functional completeness. Using the method of formalized functional completeness analysis allows us to assess the level of compliance of systems with the requirements at the stage of preliminary analysis, form a group of systems that have the same functional completeness and analyze them by other criteria. Based on the formalized analysis of functional completeness, the choice of the Autodesk Inventor system for the development and research of a new design of the mechanism for moving a tunneling explosive-bulk complex was made. It was used to generate the shape of the support frame of the complex in conjunction with the movement mechanism and made a preliminary analysis of the safety margin of the metal structure. The value of the coefficient of safety margin, taking into account the gravity of the structure with a different combination of influencing factors, ranges from 20.11 to 43.2. This makes it possible to conduct research under load in critical operating modes.

Keywords: computer-aided design systems, functional completeness analysis, formalized analysis, three-dimensional modeling, animation, superiority graph, similarity graph, absorption graph
