Modeling the characteristics of a bottom trawl

The purpose of the work is to create software for calculating the structural, geometric and strength characteristics of mesh bottom trawl structures, intended for modeling technological and hydrodynamic processes of trawl structures.Methods used: The software “Calculation of the structural, technological and power characteristics of a bottom mesh trawl” is written in C++ in the Embarcadero RAD Studio software development environment and is designed to run on the Microsoft Windows 10 operating system.Novelty: based on the results of experimental studies, mathematical and simulation models of the mechanics of trawl structures were analyzed for the first time and software was developed that allows calculating the characteristics of mesh trawl structures, including material costs for the manufacture of trawl structures.Result: The software displays the static process of trawling a mesh bottom trawl, as well as the output technological (for the technologist), geometric and power (for the designer) characteristics.Practical significance: the developed software is expected to be used in the future as a simulator module for training aquatic organisms getters, trawl masters and assistant captains for production.
