On the issue of dynamics of two-tier mechanical hydroponic installations with rigid load-bearing elements

Abstract

Hydroponic green forage (HGF) is a high-quality ecological product containing a full range of required nutrients and vitamins. A two-tier hydroponic installation with rigid load-bearing elements has been developed at Kuban State Agrarian University named after I. T. Trubilin. The purpose of the research is to determine the strength and mass complex ratios that ensure stable dynamics of movement of all elements of the system during the operation of a two-tier hydroponic installation. The derivation and solution of differential equations of the dynamics of the elements of the installation is given. As a result of experimental studies, it is proved that the maximum deviation of the center of mass of the system, tray-crop-guides does not exceed 15 cm. Based on theoretical studies, the ratio of the parameters of the system under consideration was determined, in which there is no beating phenomenon. The lengths of the load-bearing elements should not be different, and the ratio of the weights of the loaded and free trays should vary within 0.15–0.25.
