Energy analysis of motor pump units
Čenč, Samuel ; Štigler, Jaroslav (referee) ; Klas, Roman (advisor)
The bachelor thesis includes description and classification of hydraulic pump units. Individual types of hydraulic pumps, their area of use, advantages and disadvantages, and the method of regulating the output hydraulic parameters are described here. The thesis also includes a brief description of electric drives, whcich are used as a source of mechanical energy to drive hydraulic pumps. The purpose of the first part is to point out that there are two main ways of regulating the output hydraulic parameters. This is the regulation by changing the geometric volume of the hydraulic pump and the regulation by changing the speed of the electric motor. In the main part of the bachelor thesis attention is paid to individual conceptual solutions of hydraulic pump units. The essence of the regulation of hydraulic variables, the principle of operation of regulation in selected representatives regarding their dynamics is explained here. This is followed by experimental verification on real representatives of hydraulic pump units, which enables a deeper insight into the issue of hydraulic power units regulation and the course of electrical and hydraulic variables during the transient state.

Smart materials application in hydraulic systems
Montag, Jakub ; Klapka, Milan (referee) ; Kubík, Michal (advisor)
This thesis deals with the application of smart materials in hydraulic systems. In the first part, the hydraulic systems themselves and smart materials are described. This is followed by specific smart materials, where the principle of function, in which fields they can be found, applications in hydraulic systems and their advantages and disadvantages are described. Finally, the materials are summarised and compared with each other.

Technologies of feedpump water to 100 kg/hour
Holčapek, Josef ; Fiedler, Jan (referee) ; Škorpík, Jiří (advisor)
The aim of my work is to research the field of pumping technology, specify the requirements for feed pumps for small energy blocks, determine the types of feed pumps and their properties. The next task is to design a connection of a selected feed pump in a system with a piston steam engine with a power of 2 kW.

Optimization of Hydraulic System and its Components for Commuter Category Airplanes
Kameník, Luboš ; Rousek, Miroslav (referee) ; Hlinka, Jiří (referee) ; Třetina, Karel (advisor)
The dissertation thesis deals with optimization of the selected areas of the hydraulic system for small and medium transport aircrafts. Newly developed small aircraft EV-55 is a representative in the category of the small aircrafts . The selected areas of the hydraulic systems , important and useful for domestic producers of the hydraulic devices and whole hydraulic systems for the airplane EV-55 , are subjected to optimization efforts in the dissertation thesis. Design parameters of the hydraulic system (type of hydraulic source, level of pressure, weight of connecting tube), hydraulic devices ( tribology, machining process), simulation of the servomechanism and areas of diagnostic of technical status of the hydraulic system are optimized in the dissertation thesis.

Robotic hand
Pizúr, Lukáš ; Levek, Vladimír (referee) ; Šteffan, Pavel (advisor)
The aim of this work is to design a robotic hand, which will be controlled by wireless Wi-Fi, will be equipped with a camera and for easier operation will be designed control glove. The first part of the thesis is a theoretical analysis, various variants of sensors are described, which can be used for motion detection, each drive units and their control. Next chapters are focused on used electronic modules and microcontrollers. The second part is practical and is focused on the mechanical design of a five-finger robotic hand and fixing to a robotic arm. Also described is the control electronics of the entire robotic hand and the programmed firmware. Next, the design and implementation of the control glove is described. The last chapter describes the programmed application for the Android operating system.

Development of aircraft systems
Sokol, Filip ; Kaddour, Mirvat (referee) ; Trefilová, Helena (advisor)
The bachelor thesis with the name „Development of aircraft systems“ deals with development of flight control, electrical, hydraulic and fuel systems of aircraft type CS-23 and CS-25. The thesis is divided into particular chapters; each one concerns with description of particular system. The development is always mentioned at the beginning of each chapter and the rest is dedicated to basic description. There are mentioned the latest trends in flying control of the aircraft and a description of gradual transition into concepts More Electric Aircraft and More Electric Engine in the end of the thesis. The very end is comprised of comparison of aircrafts according to the aircraft systems they use.
