Strain, stress and strength analysis of the high pressure compound vessel by finite element method
Koutský, Jiří ; Suchánek, Miroslav (referee) ; Vrbka, Jan (advisor)
Strength and strain analysis of high pressure compound vessel, which is used to produce superhard materials (for example synthetic diamond). This work was elaborated to compare the stresses and strains calculated by Prof. Jan Vrbka making use of the FEM program ‘Prokop’17 years ago with those gained with the contemporary FEM Ansys program. The vessel is loaded by internal pressure of size 6 GPa. The elastic-plastic material be-haviour is taken into account. Real value of friction between rings and non-uniform temperature field is included into the calculation. The process of assembling the compound vessel is simulated step by step.

Selected designing works on the acid water stripping process
Motyka, Ondřej ; Kilkovský, Bohuslav (referee) ; Jegla, Zdeněk (advisor)
The diploma thesis is focused on selected designing works related to the design of a specific process of acid water stripping. The main purpose of the work is to describe the procedure and the obtained results for these performed design work based on the relevant assignment and the process requirements. In the introductory two chapters, the work focuses on process introduction and description of main process equipment. The following chapters are devoted to the description of the designing works, specifically simulation of the process in CHEMCAD, design calculation of the spiral plate heat exchanger for feed preheating, creation of 3D model and drawing documentation using AutoCAD Plant 3D and lastly strength analysis of the selected pipeline. The main outputs of this work are mainly generated result reports from the process and equipment simulation and strength analysis of the solved pipeline route, 3D model of the process and selected technical and drawing documentation. At the end of the diploma thesis, the performed activities and their outputs are summarized and evaluated.

Skip loader NKR130V
Derka, Lukáš ; Ospalík, Zdeněk (referee) ; Kašpárek, Jaroslav (advisor)
This master’s thesis deals with a strength analysis of the main frame and loading arms of a skip loader. For a calculation of load states is used a dynamic simulation and its results are used as a boundary conditions for the strength analysis using finite element method (FEM). The results of the analysis is evaluated and on theirs basis are designed a construction improvements. The part of the thesis is drawings documentation of the construction improvements.

Design of the manure spreader
Pacher, Ján ; Molva, Martin (referee) ; Kašpárek, Jaroslav (advisor)
The diploma thesis deals with the structural design of a solid manure spreader and the subsequent strength control of self-supporting construction. The introduction of the work consists of a research analysis of current design solutions of spreaders on the market with similar parameters as in the assignment. Subsequent chapters deal with the conceptual design of the spreader, preparation of the calculation model, suitable replacement of the components and evaluation of the strength analysis itself. The diploma thesis is accompanied by partial drawing documentation. The work was created in cooperation with ZDT Nové Veselí.

Stiffness estimation at the machining head and the strength analysis of the moving parts of the machining center MCV 1220.
Zbožínek, Martin ; Houfek, Martin (referee) ; Vrbka, Jan (advisor)
Main objective of the work was to estimate the possibilities and the limits of elementary stress and strain analysis of the construction. At the beginning it was necessary to simplify the problem to the 1-D bar problem. The calculation was performed for three typical loading cases, namely for the middle and the border position of the machining head. The contact forces and momentums and the displacements at the machining head have been calculated. The obtained results were then used for the stiffness evaluation of the construction at the machining head. The strength analysis of the moving parts of the machinig center has been done, too. Modern software products (Autodesk Inventor, ProENGINEER, ANSYS Workbench, Maple, Mathcad, etc.) were used for the calculation. The results were compared with The Finite Element Method results.
