Subject aims expressed by acquired skills and competences

Students in the course apply knowledge of the subject Hydraulic elements and systems and applies them to the hydraulic systems of working and production machines. Students will learn the function of selected working and production machines and will be able to design a hydraulic drive or transmission. They can analyze the characteristics and behavior of the machine and drive and design or modify its control according to the requirements of the assignment. They will get acquainted with specific problems of individual machines and their drives, such as mobile machinery chassis drives, hydrostatic transmissions of mobile machines, drives of mobile working machines superstructure, energy-saving hydrostatic systems, accumulator systems, emulsion and water hydraulics etc.
