Hydrobike - feasibility study
Kunovský, Lukáš ; Kárník, Jan (referee) ; Štigler, Jaroslav (advisor)
This bachelor thesis presents a project of hydraulic system which is intended specifically for bicycle drive and is realized through hydrostatic transducers. It gives information about necessary components and about the procedure of their selection. In this procedure it focuses particularly on weight reduction and loss minimization. Apart from the considerations as such, it also analyzes prior concepts and adopts suitable improvements from these. In the presented plan it demonstrates a method of effective verification of the real parameters of the whole as well as of the partial components.

High pressure hydraulics in agricultural machinery
Pavlík, Václav ; Kárník, Jan (referee) ; Soukup, Lubomír (advisor)
This bachelor thesis provides an overview of the most used ways of converting kinetic energy into pressure energy and the other way around by using hydrostatic converters. It is focused on the issue of high-pressure hydraulic mechanisms in agricultural machinery. In the next section I focused on getting an overview of the function of sophisticated hydraulic systems in current tractors and calculation of heat losses of lifting weight by front three-point hitch. For solving was used Bernoulli equation for real flow in pipes.

Radial piston pump
Kapoun, Lukáš ; Šperka, Oldřich (referee) ; Klas, Roman (advisor)
This bachelor thesis contains a basic division of hydraulic pumps. Different types of these hydraulic pumps are presented along with basic computational equations and characteristics. The main part of this thesis is devoted to the description of design of radial piston pump including modifications and kinematics of its operation. The size of pulsation flow, influence of hydraulic pump parameters on their size and continuity of working fluid supply are observed. The thesis is concluded with the evaluation of the issues concerned and supplemented with graphs.

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.
