Abstract

Improving energy efficiency of devices and systems has economic and ecological importance. Applicable hydraulic, magnetorheological, and magnetodynamic control devices consume large amounts of energy, therefore, perfection of their constructions and optimization of working processes are important research tasks. The use of magnetorheological, magnetodynamic, and ferrofluid control devices with nonstationary electromagnetic fields reduces power consumption of drive systems, increases their accuracy, reliability and durability, and raises operating temperature and pressure. The paper presents variations of original constructions of new generation magnetorheological and magnetodynamic devices with rotating and helical control electromagnetic fields, which are used for the regulation of fluid flow characteristics. The application of such regulating devices cannot only improve energy efficiency; it can also increase operating pressures and reduce dependence on temperature factors of their characteristics. Installations of ferrofluid control elements with nonstationary electromagnetic control fields in hydraulic devices contribute to increase in energy efficiency of hydraulic systems and improve their performance. Similar hybrid hydraulic systems have higher response rate to control signal and maintain stability of flow characteristics. Hybrid hydraulic systems include simple geometry of operating cavities and exclude movable mechanical elements. The constructions with movable mechanical elements have significant changes in geometry of operating cavities by influence of erosion processes. Original hybrid hydraulic device construction is presented in the paper. Developed magnetorheological and magnetodynamic devices also have simple geometry of operating cavities. The simplification of structures of devices and systems obviously decreases material consumption for their production, speeds up technological processes, increases profitability of enterprises, and reduces negative impact on environment.
