The course Design of hydraulic mechanisms, students learn the principles of creativity in the design of simple and complex mechanical and technological equipment with hydraulic mechanizmem. Emphasis is placed on energy-saving hydraulic circuit structure, its high quality of energy and information transfer with respect to reliability, longevity and fulfillment requirements of the technological process. Particular emphasis is also placed on the design of parts of hydraulic circuits, their design, calculation of basic parameters and modeling of static and dynamic behavior of the hydraulic mechanism when changing input parameters of the machine.
