Belt conveyor
Gelnar, Václav ; Škopán, Miroslav (referee) ; Řezníček, Milan (advisor)
Bachelor thesis is about a design of a belt conveyor for crushed limestone. In the first part are belt conveyors designs options summarized. The second part consists of a calculations based on ČSN ISO 5048 standard. In the thesis are designed basic parts of a conveyor. In the last part the stress and forces on the drum and the bearings lifetime are calculated

Design of elevator for pallets
Hájek, Lukáš ; Winkler, Tomáš (referee) ; Škopán, Miroslav (advisor)
The diploma thesis is focused on the construction design of elevator for pallets with car seats weighing 200 kg. This device is proposed for vertical transport of the load between two working positions which are separated by 6m. Part of the pallet hoist is a roller conveyor attached on a lifting frame. The roller conveyor allows loading and unloading pallets from the fixed roller conveyors in the lower and upper station. There are the functional calculations of important parts, strength control of traction belt and shaft of driving pulley drum. By FEM (Finite Element Method) is detected stress distribution of the lifting frame. Parts of the annex are the manufacturing drawings of the lifting frame, shaft of driving drum, the driving station and drawing of the whole assembly vertical conveyor. Furthermore, the timing diagram function for one cycle, risk analysis and FMEA.

Belt conveyor for gravel
Zeman, Vít ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
The bachelor's thesis deals with the design of a belt conveyor for the transport of gravel. The used machine parts occurring in belt conveyors are analyzed here. The work contains a computational part focusing mainly on the design of drive power. The conveyor is composed of existing manufactured components, as well as components designed by me. The resulting design of the belt conveyor is modeled and described by assembly drawings. The work focuses on belt cleaners. Their possible location and construction are discussed in the research part.

The Spectrum analysis of different single drums from a drum set differently tuned and played by different drumsticks
Cvetler, Dominik ; Mojdl, Edgar (referee) ; Jirásek, Ondřej (advisor)
The bachelor thesis deals with the analysis of the spectrum of membranophones, more precisely drums from the drum kit. Spectrum analysis evaluates aspects that affect the instrument’s spectrum, especially its inharmonicity and the generation of noise or tone modes. The aspects examined are the impact of the drumsticks hardness, the impact hit point on the drum membrane, the tuning of the resonance membrane and the presence of the tailpiece. The thesis examines inharmonicity in the spectrum with harmonic ratios between individual components in bands of harmonic series. The thesis also describes individual drums in terms of organology, drumsticks and membranes used for drums, the theoretical basis of creating membranophones sound and the way in which the measured samples were recorded and processed.

Device for stringing cable on a drum
Polách, Martin ; Pokorný, Jan (referee) ; Kašpárek, Jaroslav (advisor)
The thesis deals with the design of a cable spooling device on a spool drum under different modes of operation of winding. The focus is on the calculation and design part, where the calculations include the functional dimensions of the individual components and the force effects emanating from the load generated during winding. The design part includes the design of the individual components. Finally, an analysis of the selected structural nodes under different winding modes was performed. This work includes drawings containing the overall equipment assembly, subassembly of the weldment frame and shop drawings.

Návrh malého (vířivého) bubnu z vertikálních bloků a jeho výroba
Beran, Ondřej
Bachelor thesis is confused on design and production of snare drum of the vertical blocks. You can see technological process and production of drum since raw board throught wood processing, how to put brum body tohether, gluing, till surface finish. Next there is a testing of acoustic properties of created drum and methodics of testing. There is comparsion between created drum and mass production drum.

Belt conveyors - special constructions
Hejl, Radek ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
The aim of this bachelor thesis is to draw up an overview of manufacturers of belt conveyors and their individual components together with clarification of functions and construction of selected units. The work includes basic division, overview of manufacturers of different types of belt conveyors, diagram and description of individual parts, analysis of conveyor belts, drums, belt cleaners and others, together with the overview of manufacturers of these components. It also contains an assembly drawing of the selected unit.
