Derrick of the filling car of coke-oven battery
Hurník, Štěpán ; Plachký, Pavel (referee) ; Pokorný, Přemysl (advisor)
This master´s thesis deals with a proposed design of the derrick of the filling car of a coke-oven battery, which is used for working with unit loads, repairing and maintenance of the filling car and cleaning of the battery risers. In the first part a solution concept was chosen. For this concept a main steel structure was designed, which was controlled in stress analysis by the FEM program I-DEAS NX 11. Further, the main parts of the lifting and travelling mechanism were calculated using specified parameters. In the conclusion of this thesis the results summary of specified targets is stated. Assembly drawing is in the annex of this thesis.

Cranktrain of three-cylinder in-line disel engine
Kovář, Pavel ; Ramík, Pavel (referee) ; Píštěk, Václav (advisor)
This master’s thesis describes design and comparison of three variants of the crankshaft in-line diesel engine for commercial vehicles. The work focuses on working with programs for 3D modelling and analysis proposed models, to be able to work under difficult conditions. Part of this work is a computational modal and strength analysis.

Design of tank container for storage of petroleum products
Bezděk, Lukáš ; Nekvasil, Richard (referee) ; Létal, Tomáš (advisor)
This diploma thesis presents design of oil storage container type ISO 1CC. The container is designed according to ISO standards. The standards prescribe or limit some of the container dimensions, other dimensions are derived from specific purpose of the container. The container can be considered either as a transport container (empty) or as a stationary tank (full). Therefore, the load conditions are given by ISO for transport containers in the first case and by ČSN EN for the latter. The goal is to design and evaluate various container designs by FEM (finite-element method) analysis.

Forks for handling logs
Seďa, Marek ; Juřík, Josef (referee) ; Škopán, Miroslav (advisor)
This master’s thesis with product design forks for handling logs as attachments for tractors Zetor Forterra the specified load capacity 1200 kg. The work is mainly focused on the design frame and fork clamps, the necessary calculations and ultimately strength check of designed structures. The work is also addressed in detail the linear hydraulic motor used for the rotational movement of the jaws, including the calculation of fork. Then there are the design calculations and stress analysis of journals. It also checked the stability of the machine. Stress analysis is performed for different load conditions and the jaw frame finite elements. As another part is making all the drawings.

Hydraulic pullers
Pavelka, Roman ; Malach, František (referee) ; Malášek, Jiří (advisor)
This diploma thesis deals with the mechanical proposal of hydraulic puller. Furthermore, it includes the detail design solutions. The project also includes the calculation of the hydraulic puller parameters: maximum pushing force is 60 kN, speed of movement is 0.1 m s-1. This work also contains of stress analysis FEM with I-DEAS software. Following part deals with the design of hydraulic circuit for driving puller. At the end of work there are options for replacements of hydraulic puller by mechanical systems.

Connecting rod of gas V-sixteen engine
Laštovica, Karel ; Ramík, Pavel (referee) ; Píštěk, Václav (advisor)
This diploma thesis deals with a design of a stationary engine connecting rod, its stress analysis and its safety factors. The thesis is divided into several parts. At the beginning there is a short research of connecting rods construction and a description of the engine. Then the main dimensions of a piston group and a connecting rod are defined and its 3D model is created. Next, the calculations of forces acting on the connecting rod in the crankshaft mechanism, are carried out. The following part deals with a stress analysis of the model created by MPK. From the obtained stress results, the safety factor at fatigue limit in chosen places of the connecting rod is calculated. In the conclusion, the results of the stress analysis and set safety factor level, are recapitulated.

The analysis of frame synchronous generator
Marada, Ondřej ; Střelková, Radka (referee) ; Pokorný, Přemysl (advisor)
The thesis is focused on the examination of the utility of a synchronous generator of a small hydroelectric power station in the case of a change of working position of the machine. The utility will be measured on the basis of the examination of deformations and state of stress of the frame of the generator for the present running (with vertical axis of rotation of the generator) and subsequently for modified running (with horizontal axis of rotation). This will be accomplished partly on the static shell model by finite element method and consequently on the simplified dynamic model.

Swing axle of a truck
Holbík, Ondřej ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
The main purpose of this diploma thesis is to design a swing axle of a truck for 4x4 chassis without wheel reduction gears. The study consist of two parts. The first part contains designs of main parts of the axle, mechanism of suspension and steering. The second part contains the gears housing stress analysis using the finite element method. The housing of gears is the arm of the swing axle, which is the main part of the chassis.

Powertrain of racing Wankel rotary combustion engine.
Blažo, Marek ; Blaťák, Ondřej (referee) ; Zháňal, Lubor (advisor)
The main aim of master’s thesis was to handle the computing proposal and the construction design of the powertrain of racing Wankel rotary engine with 300 kW power output and in the case of 9000 speed per minute. On the basic of these values was made the primary design of the rotary engine, design of the eccentric shaft and rotor housing. Mechanical stress and torsional vibrations of the eccentric shaft were analyzed by using the course of indicator diagram.

Formula Student Vehicle Frame Optimization
Krkoška, Kamil ; Porteš, Petr (referee) ; Ramík, Pavel (advisor)
The goal of this diploma thesis was to create optimalizated frame design for Formula Student/SAE. Basic requirements were, that new design must meet the newest Formula Student/SAE rules and other various requirements. In the thesis are built up an overview of most important rules and also an overview of previous frame designs. Next are described design process of the new frame and its stress analysis in FEM software. Main attention is given to analysis of torsional stiffness. The results of analysis are compared to previous frame designs and to parameters of Formula Ford. There are also given recommendations and other possibilities for further frame design development.
