SOME QUESTIONS OF COMPUTER DYNAMIC GEOMETRIC MODELING OF TECHNICAL OBJECTS ON THE AIRPLANE EXAMPLE

Abstract

The modern stage of the scientific-technical progress is based on the wide use of information technologies for creation of different technical objects. Therefore, the elaboration of new effective methods for computer-aided design is relevant now.The purpose of this article is the development of the theoretical basis for the computer dynamic geometric models of different technical objects. The urgency of this problem is caused by the special importance of the geometric processes in the design, manufacture and operation of industrial products. Computer technologies and the corresponding methodical, mathematical, information and software support offer great perspectives in this direction.The geometric models perform an integrating role for many computational models of technical objects. This applies to the design models, the strength models, the technological models etc.The proposed methodology of the dynamic geometric modeling is illustrated by the example of the modern airplane as one of the typical representatives of the complex technical objects. The basic techniques of this methodology were shown. The main emphasis was placed on their universal role for computer modeling of various technical objects and processes. The general classification of used geometric objects was made. The dynamic transformations of various geometric objects were arranged. Some perspectives of further improvement of proposed techniques were analyzed.The outlined information is the theoretical base for the development of the appropriate software for computer-aided design of different technical objects and processes for their manufacture and use.The proposed methodology is a further improvement of structural-parametric approach for geometric modeling of technical objects which was developed by the scientific school of applied geometry at National Technical University of Ukraine «Kyiv Polytechnic Institute».The considered methodology of computer dynamic geometric modeling can be the basis for the complex optimization of various technical objects. This requires the further intensive theoretical researches and introduction of the received results into practice.
