Furnace design
Stříž, Michal ; Nejezchleb, Radek (referee) ; Nekvasil, Richard (advisor)
This master´s thesis deals with issues of tube furnaces in the process industries, especially with a design of a transfer pipeline, which is one of the main parts of the furnace. According to the requirements, designed pipeline is stress analyzed using the two pipeline programs Japar and Caesar II, that are briefly described. In addition to this design several variants of analysis are performed and the results are compared. Comparison helps to explain the diversity of the programs. For example, the effect of elbows on the stress analysis. The master´s thesis also describes the factors that affect the working life of the furnace.

Design of platform simulator
Hlaváček, Pavel ; Macka, Jiří (referee) ; Škopán, Miroslav (advisor)
The diploma thesis deals with an analysis and the strength check of selected componenets of a parallel mechanism containing six degrees of freedom. The device uses crank mechanisms as chain guides. The strength calculation takes advantage of the finite element method. The paper also suggests a design of selected components contributing to a reduction of the maximum stress von misses (according to the HMH condition) causes by the load.

Overhead travelling crane 125t
Peprník, Pavel ; Zimola, Lubomír (referee) ; Pokorný, Přemysl (advisor)
This diploma thesis deals with the assessment of drafted steel construction of overhead travelling crane by using finite element method. The crane’s lifting capacity is 125t/32t. It is going to be placed in hall of Slovácké strojírny, a. s. in Uherský Brod. Span of the crane is 25.8 meters, wheelbase is 6.7 meters and lifting height is 17 meters. My work contains analysis and assessment of crane construction with a load of fatigue according to ČSN 27 0103.

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.
