Methodology for Determining the Characteristics of Midwater Trawl Structures
https://doi.org/10.36107/spfp.2022.324
Abstract
Research background: Foreign software products such as Mathcad, AutoCAD, etc. are used in educational organizations and at enterprises of the extraction of hydrobionts of Federal Agency for Fishery in order to study the mechanics of trawl structures, as well as to perform their design procedures.
The gap to be filled in the existing knowledge and the purpose of the study: In this article, we describe the software product “Calculation of structural, technological and power characteristics of a mid-water trawl”. Kaliningrad State Technical University and “DigiTech Laboratory” offers a phased import substitution of existing software products.
Materials and methods of research: At the first stage, it is proposed to replace Mathcad with the software product “Calculation of structural, technological and power characteristics of a mid-depth net trawl”. At the second stage, the replacement of AutoCAD with the software product “Computer-aided design system for commercial fishing gear”. To solve a number of problems of trawl structures, namely their mechanics and design, it becomes necessary to use software that allows you to calculate and justify the design, geometric and power characteristics of trawl structures (bottom and mid-water). These characteristics include: cycles of cutting netting plates, mass of netting plates, dimensions of netting plates, hydrodynamic resistance force of warps, cables, rigging and net part of the trawl structure.
Results and their application: Computer program “Calculation of structural, technological and power characteristics of a mid-water trawl” was developed by “DigiTech Laboratory”. Software for calculating the characteristics of trawl structures includes the calculation and design of mid-water trawls.
