Abstract
Currently, composite products are widely used in various industries, such as aviation, shipbuilding, chemical, oil and gas industries due to the unique properties of these products: high strength, radio transparency, resistance to chemical components. At the same time, the range of these designs is constantly expanding, their complexity is increasing, and the requirements for product quality are also increasing. In connection with the improvement of winding process technology, electric drives used in winding equipment have become subject to more stringent requirements for speed and the ability to adapt to changing operating conditions. It is possible to fulfill these requirements only by using modern means of controlling the winding process and taking into account all the features of the process of manufacturing products from composite materials. This necessitates the improvement of electrical systems for tensioning winding mechanisms. The elastic dissipative properties of the electric drive of tensioning devices used in winding products made of composite materials have not been studied to date. Known methods for the synthesis of electric drives do not take into account these features of the processes of winding products made of composite material and therefore do not allow the synthesis of electric drives with the required dynamic characteristics. The work investigated the elastic-dissipative properties of the composite material used in winding products. The studies were carried out on a mathematical model that describes the composite tape during winding, taking into account possible changes in parameters during equipment operation. It is shown that an elastic composite tape can be described by a second-order link. As a result of the research, parameters were obtained that connect the winding technological process with the properties of the material. To obtain the mathematical dependence of the damping coefficient and the time constant of the second-order link, the experimental design method was used. Variable parameters and the limits of their change were determined and a matrix for planning experiments was compiled. After processing them, it was possible to obtain simple analytical expressions. Refining the mathematical description of the winding path will make it possible to synthesize faster electrical tensioning systems and improve the quality of wound products.
