Ієрархічна система математичного моделювання визначення послідовності складання виробів

Abstract

У роботі розглянута одна з глобальних задач машинобудування – розробка ієрархічної системи математичного моделювання автоматичного складання об'єктів. Пропонуються нові принципи побудови математичних моделей техпроцесів, викладені наукові вишукування в цій області і подана послідовність автоматичного складання об'єктів, розроблена за допомогою ЕОМ.One of the main tasks of engineering industries are retooling of enterprises based on accelerating the introduction of scientific and technological progress. Assembly – the final and decisive stage of the production process, from which performance depends largely on the quality of machines. The complexity of assembly covers 25...60% of the complexity of manufacturing products. Currently, about 25% mechanized and automated assembly is 6%. Continuous improvement and complexity of machine designs resulting in increased complexity, increased requirements for reliability and build quality. With the present level of automation should be involved in the assembly process a large number of highly qualified specialists. In this connection, automation assembly production dramatically increases productivity, technical level and quality of products and accelerates the solution of social problems. Low levels of assembly production can be explained as follows: perform assembly work requires high flexibility of technological equipment; no rational methodological basis for the creation of automated assembly systems, assembly not developed classification systems and principles of unification. If the scientific and technical literature some mechanization and automation of assembly operations, the issues related to classification and structure optimization of automated assembly technology systems, practically designed. The paper considered one of the global problems of engineering – the development of a hierarchical system of mathematical modeling automated assembly facilities. Proposed new principles of construction of mathematical models of technical process set out scientific research in this field and given the sequence of automatic assembly of objects designed by computer. Designed iterative method for determining the sequence assembly of products using computer technology allowed the design to reduce the sequence assembly of products, reduce the cost of their development, improve the quality of applied solutions. Reducing the institutions and positions in the preparation resulted in a reduction of the production cycle, which ultimately reduces the amount of working capital, accelerating their turnover, reduces the cost of the product.
