Hydraulic drives of hoisting drums
Vořech, Jiří ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
This bachelor´s thesis deals with hydraulic drives of hoisting drums, their sorting and description of their parts and components. It also pays attention to comparison of particular possibilities of hoisting drums with hydraulic drive rationale. A 3D model of a suitable example of technical solution for the purpose of explaining the principle of the function is a part of this work as well as a hydraulic circuit diagram.

Testing of aircraft hydraulic systems
Suk, Filip ; Bencalík, Karol (referee) ; Třetina, Karel (advisor)
My bachelor thesis “Testing of aircraft hydraulic systems“ discusses the problems of testing particular components and complete hydraulic systems. In the first part of my work, there are specified all regulation requirements that are to be fulfilled by hydraulic systems and test conditions for testing of flight control systems. The next parts deal with the way of testing particular hydraulic elements and hydraulic liquids. The last part of my bachelor thesis is dedicated to the testing's principle of hydraulic system of landing gear including a concept for instrumentation.

Technicko-ekonomická analýza hydrostatických axiálních převodníků.
Vaverka, Ondřej
This thesis focuses on developing a general summary and description of the function of the hydrostatic drives used in modern agricultural harvesting technology. The following is a list of practical application of the hydrostatic drives on the machine at the same time giving a description of the function of the system. The third part is an evaluation of the measurement of the five hydraulic pumps hydrostatic ground drive combine CLAAS Lexion 560. The hydraulic pumps are classified according to the operating hours, the graph is plotted Q-p characteristics of the pumps and in the end is compared to the wear depending on the operating time. The last part of the thesis deals with the analysis of damage of the hydraulic pump drive combine harvester and determining the cost to repair the drive according to the selected type of repair.

Hydraulická štípačka dřeva - koncepční řešení
Pospíšil, Jakub
This thesis provides a comprehensive overview of different concepts of currently produced hydraulic log splitters. It analyses the most important functional units, their structures, the principles of auxiliary mechanisms that facilitate work and improve safety. Log splitters are classified and evaluated according to the most important criteria. The thesis presents different ways to drive log splitters with an emphasis on the efficiency of their use. Thanks to the possibility to control the operating performance, speed is increased while maintaining high cutting forces. Conclusion of the thesis contains draft of author's basic hydraulic, strength and operational parameters calculations.
