Abstract
The purpose of the work is to develop mathematical dependencies of the physical and mechanical characteristics of twisted fishing materials. The creation of a mathematical apparatus for modeling the geometric and force parameters of twisted fishing materials is a priority task for the development of new materials for industrial fishing and aquaculture.
Methods used: Mathematical analysis of the obtained experimental data on the relative elongation and breaking load of fishing materials in order to determine the dependence of the forces on the structural and geometric characteristics of twisted fishing materials.
Novelty: Based on the results of experimental studies, approximating dependences of relative elongation and relative breaking load on the continuity of the product, as well as on the ratio of surface and longitudinal tension of twisted fishing materials made of polyamide, polypropylene and polyester, were obtained for the first time.
Result: Mathematical dependencies make it possible to calculate the relative elongation and breaking load of twisted fishing threads and ropes made of polyamide, polypropylene and polyester within an accuracy of 90%.
Practical significance: Mathematical modeling of the physical and mechanical characteristics of twisted fishing materials allows, when designing industrial fishing tools, to set, taking into account the safety margin, the design characteristics of fishing products that are made of polyamide, polypropylene and polyester.
