High loading shovel for telehandlers LM1345 Turbo
Dragan, Lukáš ; Kubín, Martin (referee) ; Škopán, Miroslav (advisor)
This diploma thesis follow up the structural design high loading shovel for telehandlers LM1345 TURBO by New Holland. The introduction processed basic characteristics and parameters of the machine and material which will be in operation most frequently transported by the shovel. The work includes static analysis load acting on the shovel and frame when the machine is operating, strength calculations and the design and control of the peg.

Construction of hydraulic bending machine of steel sections
Kluka, Ladislav ; Pavlík, Jan (referee) ; Matějka, Petr (advisor)
This master’s thesis deals with design of a hydraulics bending machine. Bending machine will be used primarily for bending reinforcement bars in the shape of stapes. It consists of bending, sliding and chute system, which are located in the machine frame. Drive of each system is provided by a rotary and two linear hydraulic motors. Then there is described a hydraulic system and selection of its most important parts. Work is supplemented by visual documentation in the form of images of individual systems were processed in a CAD system Inventor 2010

Filament Winding Machine
Dorňák, Michal ; Hampl,, Štěpán (referee) ; Foller, Bronislav (advisor)
The aim of this diploma thesis is the proposal of solution of three-axial winding machine for winding technology of rotary profile. Winding materials are continual springs of carbon, aramid or glass fibre impregnated by resin. The main construction change of the machine compared to commercial available solutions is the use of linear motor as a frame element instead of roller screws or toothed chain. Linear motors have higher dynamics of the movement and they can reach higher speed compared to other solutions, which guarantee increase of the machine productivity. The main importance is put not only on the functionality but also on the low price of this solution. The 3D model of the mechanism is created in the program Inventor 2009.

Design of a robotic cell for hydraulic pipes moulding
Bartošek, Jindřich ; Kubela, Tomáš (referee) ; Pochylý, Aleš (advisor)
Předmětem této diplomové práce je návrh robotické buňky pro tvarování hydraulických trubek. Práce obsahuje analýzu technologie tvarování trubek a zdůvodnění potřeby automatizace celého procesu. Z návrhů jednotlivých konstrukčních uzlů byly vybrány nejvhodnější řešení a ty pak byly aplikovány při konstrukci buňky. Robotická buňka byla navržena s ohledem na bezpečnost provozu, funkčnost a jednoduchou ovladatelnost. Na závěr je vypracováno ekonomické zhodnocení projektu. K práci je přiložen návod pro ovládání, výkresová dokumentace, model buňky a výsledky simulace.

Mechanical-hydraulic model of vehical energy regeneration
Pisklák, Jan ; Vrbka, Martin (referee) ; Nevrlý, Josef (advisor)
This bachelor thesis is a research about mathematic-physical model of vehicle’s kinetic energy regeneration. Mr. Pourmovahed A. et al. were dealing with this problem. He used the method of the determinated thermal time constants. Pourmovahed continued in study reports written by Green W. L. and Otis D.. His scientific work covers the analytical treatment which is compared with an experimental tests.

Models of vehicle´s kinetic energy recovery
Fic, Miloslav ; Vaverka, Michal (referee) ; Nevrlý, Josef (advisor)
The bachelor thesis deals with analysis of existing knowledge in the area of vehicle kinetic energy recuperation models. This analysis is mainly focused on hydrostatic regenerative braking system models. This paper introduces stances of some authors, mathematic relationships and program tools useful for simulation of these models. Afterwards is estimation of shown studies and at least is presented future development of hydrostatic regenerative braking systems. This paper gives a sight of hydraulic recuperation system problems and it could be used as the theoretical element for next research in recuperation models area.

Mechanical construction of hydraulics arm
Vodrážka, Jakub ; Březina, Lukáš (referee) ; Věchet, Stanislav (advisor)
This bachelor’s thesis deals with design of a hydraulics arm. The main purpose of this hydraulics arm is the possibility to use it in education project which is a part of hydraulics systems lessons. This arm consists from few parts which are connected together by rotary joints. This arm is actuated by linear hydromotors, furthermore there is a magnetic position sensor. Autodesk Inventor 2008 was used during the arm design process. There are three main parts in this work. First part deals with fluids systems, the second part shows the position sensor properties and the last part presents some cases of arm design with deformation verify. A lot of supplement is presented at the end of this work as pictures of the model of the arm or pictures of some parts of the model.
