TO THE QUESTION OF THE ANALYSIS OF GEOMETRIC MODELS OF MODERN SOIL PROCESSING TOOLS

Abstract

Agricultural production plays a very important role in the national economy of Ukraine. Its effectiveness largely depends on the technical means which are used. Therefore, the further improvement of the latter is an actual scientific and applied problem. At present, one of the progressive directions of its successful solution is the wide application of computer information technologies, in particular computer-aided design, for the development of the specified technical objects.

One of the generally recognized foundations for this is geometric modeling, without which it is difficult to imagine most modern computer-aided design systems. It is important that geometric models combine other models of processed industrial products into a single whole, for example, their strength, manufacturing technology, operation, etc. This ensures the implementation of a comprehensive, i.e. multi-aspect, optimization of the created product for its entire life cycle.

Effective use of computer shaping tools for certain groups of technical objects is possible by adapting the first to the second. A necessary condition for this process is the classification of existing geometric means and reproducible products in the appropriate aspects. This contributes to obtaining high-quality results of computer-aided design. If necessary, the existing shaping methodology is supplemented with new methods, techniques, algorithms, models, etc. In this way, the mutual improvement of the theoretical and practical aspects of geometric modeling and agricultural production is carried out.

The main purpose of this publication is to present the basics of the methodology proposed on the foundation of the structural-parametric approach for carrying out an integrated, i.e. combined, classification of agricultural machines and means of automated geometric modeling. As examples, some existing tillage tools were analyzed. For other technical products, the outlined concept is applied in a similar way. The article also defines the perspectives for conducting further scientific research in the considered direction.

Key words: computer-aided design, geometric models, tillage tools, agricultural production, structural-parametric shaping.
