Substantiation of the Theory of Forces Calculating in a Steel Winch Cable for Lifting Seed Material to the Upper Tiers of Hydroponic Installations

Abstract

Hydroponic green fodder (HGF) is a product containing a full range of required nutrients and vitamins. To implement this technology, it is necessary to develop not only basic hydroponic installations, but also additional devices that reduce the labor intensity of production of HGF. The purpose of the research is the theoretical substantiation of the dynamics of the system “winch – steel cable of variable length – end load. The conclusion and solution of a system of second-order differential equations with variable dynamics coefficients of elements of a lifting installation (winch) are given. In addition, dependencies have been compiled to determine the elongation and force in the lifting cable.
