Wood-splitting machine
Henzl, Lukáš ; Malach, František (referee) ; Malášek, Jiří (advisor)
The thesis describes the design of the wood-splitting machine including stress and check calculations and design of the hydraulic circuit. For structural design, it is necessary to choose the maximum dimensions of wooden logs, which have length 1,1 m and diameter 0,5 m and over. The machine structure is vertical. Another task of the thesis is a technical report of similar machines and the justification of the design concepts of splitting machine. In the thesis, there is elaborated an experiment on different types of wood splitters, stress analysis calculated by using finite element method and there is also drawn up technical parameters of wood.

Bending roll machine for Hardox
Budík, Tomáš ; Dokoupil, Vladimír (referee) ; Omes, Jiří (advisor)
This work describes the design of a dedicated three-rolls hydraulic bending for Hardox 500 without the possibility of bending sheet metal for the manufacture of pipes. The work will analyze the problem of proposed three-rolls bending, bending technology and creating of the pre-bending, the design of the adjusting hydraulic servo-cylinder, planetary gearboxes with hydraulic motors to drive the bottom rollers, a partial draft of the hydraulic circuit and the complete frame structure of bending machine with its covers.

Hooclift NKH 8A340
Doleček, Ladislav ; Ospalík, Zdeněk (referee) ; Kašpárek, Jaroslav (advisor)
This master thesis analyses hook loader NKH 8A340. For calculation of load states was used the dynamic simulation in program MSC.ADAMS. This results were used like a input data to solve the construction with finished element method. After evaluation of results were made design changes of hook loader. Part of this thesis contains drawings of modified parts of hook loader.

High loading shovel
Petro, Roman ; Lžičař, Roman (referee) ; Škopán, Miroslav (advisor)
This diploma thesis solves construction project high dumping shovel for back hoe loader New Holland B100 and B110. There are described operating conditions in the introduction, transport material and technical parameters for back hoe loader B100, B110. There are mentioned possible construction’s solutions and own design. Follow the kinematics analysis of material’s dumping and the static analysis on shovel and frame. This is connected with following peg’s control and the solidity analysis of shovel and frame for different load cases, where the MFE was used

Hydraulic and mechanical holding device of front shovel of excavator LB 115
Bělov, Pavel ; Lžičař, Roman (referee) ; Škopán, Miroslav (advisor)
This Diploma thesis solves a quick coupler design for a loader. In introduction of the Diploma thesis are mentioned two potential designes and convenient solutions. Subsequently are outlined two practicable designes of a quick coupler for a original bucket, as a data componant of the second construction design is enclosed basic strength calculation. The ending point of the thesis deals and compare with the force decrease in use of a quick coupler and appraisals achieved ascertainment.

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.

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.
