Damping Characteristics Identification for Custom-Made Winding Device

This paper aims to determine the damping characteristics needed to diminish oscillations developing in a positioning system of a winding device while under operating conditions. This damper is being selected for a specially made universal winding device designed for creating bobbins and filters made of textile, composite nanofibrous and pure nanofibrous yarns. Because some of the processed materials are inherently delicate, it is necessary to have a higher precision of support pressure control. The main focus of this work is to demonstrate practical steps in determining parameters for selecting optimal motion damper. Multiple experiments were conducted to determine the positioning spring stiffness, moving masses’ moment of inertia, and damping characteristics, which are mainly present due to friction. Using the data from experiments, the frequency response of the system was measured as well. Using available information, the optimal damping factor was determined, which will serve for the selection of a suitable damper.
