Design and technological solutions for technical systems based on the example of a sowing complex for grain crops

Abstract

In this paper, we have developed a formalized problem statement for automated design of a technical system (TS) on the example of a sowing complex (SC) and improved the methodology of decision-making information support for its design by creating a virtual model of the TS. An information-logical model, which unifies sets of data on the external environment and data processing technologies, is used for selecting the structural scheme of the TS. A procedural decision-making model allows optimal selection of standard units and mechanisms of the TS taking into account uncertainty and discrepancies in the data. The virtual model of the SC is presented in the form of a hierarchical frame structure, including parametric three-dimensional geometric models and drawings of individual units, devices, mechanisms and details, as well as attributive data. A new design of a SC for grain crops uses both standard units and non-standard devices, which provides reduction of the sowing time and energy consumption together with the possibility of using the SC as a cultivator and a disk harrow.
