Abstract

Approaches to digital design and modeling are investigated. The methods for preliminary estimation of the parameters and structure of a product being created based on a digital twin are proposed. The principle of choosing the characteristics of replaceable modules for a designed object at the stage of research design is shown. The requirements of the nature, placement and application of the target payload were taken into account. It is shown that in research design based on a digital twin, the critical challenge is to jointly optimize the characteristics of all modules and the overall configuration of the object.

Highlights

An object under design is considered as an integral system, consisting of two subsystems: – carrying platform; – a complex of payload modules
A module is understood as a structural element included in the object’s information system, designed to place the target payload [1,2,3]
When optimizing the characteristics of complex technical objects, it is necessary to provide for the possibility of changing the functional tasks of the modules based on the variation of the assigned tasks, as well as modernization reserves

Summary

Introduction

An object under design is considered as an integral system, consisting of two subsystems: – carrying platform; – a complex of payload modules (hereinafter referred to as modules). A module is understood as a structural element included in the object’s information system, designed to place the target payload [1,2,3] The characteristics of these two subsystems are closely interdependent. When optimizing the characteristics of complex technical objects, it is necessary to provide for the possibility of changing the functional tasks of the modules based on the variation of the assigned tasks, as well as modernization reserves. The reason for this is that the life cycle of the “basic platform” is much longer than that of the module. Models the details of which correspond to the information of the research design stage are used (Fig.1)
