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.

Principles and types of hydrodynamic valves
Havelka, Milan ; Himr, Daniel (referee) ; Pochylý, František (advisor)
This thesis deals with characteristics of the most commonly used valves in hydraulic systems. The aim was to create an overview of available features and define their brief characteristics. The emphasis was placed on their function and principles of task performance in a hydraulic circuit. The second part of the thesis is aimed at solving the issue of valves oscillation and subsequent optimization of constants that function as factor dampping.

Jib type crane
Knapec, Tomáš ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
This bachelor's thesis is the design development of jib type crane with single knuckle. The target of this thesis is to develop a technical report including important strength calculations, schematic hydraulic circuit design and creating complete drawings of jib type crane that is designed for installation on mobile devices. Desired parameters of this crane are allowing horizontal rotation in 360° a vertical between 90° and maximum load capacity 1 700 kg.

Mounting wood splitting machine
Zápotočný, Václav ; Škopán, Miroslav (referee) ; Malášek, Jiří (advisor)
Bachelor's thesis, made at the Institute of Automotive Engineering, is focused on efficiency and faster way of wood waste processing, which is caused by logging or adverse nature conditions. Next step is making the hard physical work connected with logging easier especially in hardly reachable places. The splitter design is based on easy operation, handling and its independency on non-transferable propulsion source. It has got a tendency to be a cheaper option compared to professional splitters especially for small forest companies and minor forest owners.

Wood-splitting machine
Svoboda, Vít ; Škopán, Miroslav (referee) ; Malášek, Jiří (advisor)
The objectives of the bachelor’s thesis is to make a short research about the cutting machines in general, compare the design, individual drives and the parameters of these machines. The next part is the emphasis on the actual construction of the machine, which is another goal of the work. At first, the frame is designed, then the hydraulic circuit of machine is designed by calculating and the last part deals with control and supporting calculations splitter component elements. The basic drawings of selected components of the splitting machine are parts of the work.

Dozer of non-homogeneous materials
Henzl, Lukáš ; Hloska, Jiří (referee) ; Malášek, Jiří (advisor)
This thesis describes the design of the hydraulic dozer of inhomogeneous materials, especially for ploughing of manure from the stables of corridors, with the possibility of dozer changes in working widths as needed. This machine will be attached to the telescopic handler Manitou MLT 845 – 120 LSU. Another part of the thesis is the technical report about similar machinery and the justification of designed concept of the pusher block. The thesis presents important technical calculations and an overview of possible inhomogeneous materials that could be ploughed by the plow blade. The thesis includes drawings of weldment of the centre of blade and drawing of the whole composition of plow blade.

Project of hydraulic arm
Andrlík, Jan ; Škopán, Miroslav (referee) ; Malášek, Jiří (advisor)
This thesis is elaborated design of the hydraulic arm. The target is for the composition of the important strength calculations and drawings hydraulic arm, whichis designed for mobile devices. Hydraulic arm allows shooting in a horizontal 360° vertical shooting between 90° and a maximum load arm 1000kg. In the work is also a schematic hydraulic circuit design.

Micro-hydraulics system design
Pitaš, Martin ; Marada, Tomáš (referee) ; Věchet, Stanislav (advisor)
One of the main aims of presented bachelor's thesis is an implementation of hydraulic circuit by micro-hydraulics system. Bachelor's thesis has three main part. First part deals with hydraulic distribution and selection of acceptable devices of hydraulic circuit, especially their advantageousness in term of finance. Second part is devoted to the construction of fixation for the position sensor on linear hydromotor, holder for hydraulic valve and hydrogenerator. Third part describes to hydraulic circuit, right hydraulic oil for whole hydraulic circuit. The verifying calculation confirming rightness selection particular devices is here also. Autodesk Inventor Professional 2008 (chapter 3) a FluidSIM Hydraulics V 4.2 Demo Version English (chapter 4) was used as a general software.

Design a methodology of disassembly-less diagnostics systems for timber-transport trucks.
PŘICHYSTAL, Martin
The work deals with the methodology of disassembly-less procedure of hydraulic systems. The theoretical part contains the basic characteristics of fluids, hydraulic system parts description, hydraulic system elements description, characteristic of measured variables and description of diagnostic methods of the hydraulic system elements. The practical part includes the methodology of disassembly-less diagnostics of hydraulic system and verify the suitability of the proposed disassembly-less diagnostics.
