ПРОИЗВОДИТЕЛЬНОСТЬ СИЛ ТРАЛОВОЙ СИСТЕМЫ: ПОСТАНОВКА ЗАДАЧИ

Abstract

In the design process of the trawl systems, there often arises the need for their mathematical, computer and physical modeling, because in the process of physical modeling it is possible to predict the dynamic processes in the ropes and threads during operation. Automation of the process of a rope-net trawl physical modeling using information technologies is an important problem of a scientific research. The importance of creating a unified database containing information on trawl designs, history of design changes, information on the classification and coding of trawl systems, history of fishing for aquatic organisms in different parts of the World Ocean, as well as data on the fishing gear design and places of their mounting, operation and maintenance. The terms of preparation and approval of project documentation are reduced due to using 6D-control. Competent economic and resource planning, elimination of possible risks even at the planning stage lead to the lower costs and increasing labor productivity. The concepts of productivity of forces (mechanical, electrodynamic, etc.), productivity of forces of the system (technical, biological) are considered, a new parameter is introduced - the productivity of the forces of the trawl system. The postulates operating in all the trawl systems have been proved: the differential law of motion describes the relationship between the square of force applied to a material point and the resulting productivity of the forces of this point; productivity of forces exerting on a material point is equal to the second derivative of the work of these forces in time; the productivity of a system of forces of differ-ent nature exerting on a system of material points is called the productivity of the forces of the system (technical, biological, etc.).
