Design of spindle for lathe
Novotný, Timotej ; Tůma, Jiří (referee) ; Pavlík, Jan (advisor)
The diploma thesis deals with the design of headstock of turning center. The introduction of the work is devoted to a brief description of turning centers and detailed description of individual parts of headstock. The main part of the work consists of determining the characteristics of the headstock, calculations necessary for design and dimensioning and calculations using the finite element method. The result of the work is a 3D model of the designed headstock and drawing documentation.

Ultimita
Jindra, Daniel ; Kala, Jiří (referee) ; Hradil, Petr (advisor)
Structural beam and shell models were assembled in ANSYS program package. Design loads are defined according to Euro codes. Nonlinear analysis of structure has been established. Ultimate limit state of beams and cross sections were determined. Obtained results of ultimate limit state analysis were compared with Euro codes for design thin-walled steel structures.

Analysis of load capacity of selected welded structural joints under static and cyclic load
Peč, Michal ; Vlk, Miloš (referee) ; Vosynek, Petr (advisor)
Welding is a widely used method of connecting components because of its efficiency, great value and almost endless possibilities of join types. A great variability of geometrical configurations of welds is problematic due to the assessment of the weld joint. Depending on this topic this thesis was focused on the assessment of weld joints statically and cyclically. Work in the first part deals with the search of methods for evaluation of welds and depending on identified options is subsequently selected American standard AISC assessment of welded joints. The method is applied into FEA analysis and simple welded joints are evaluated. Using FEM are computed three examples on which a comparative analysis was performed. Comparisons were made with the analytical solution based on changes in the parameters of the computational model. The change is primarily related to material properties, mesh size and division of the weld on segments. On the basis of knowledge from analysis of simple joints, method was extended to more general welded joints with the possibility of determining the maximum loading force.

Alternative designs for removable connection with cover and housing of airbox
Dvořák, Milan ; Fejta, Tomáš (referee) ; Škopán, Miroslav (advisor)
The aim of this thesis is to description and comparison of solutions, demountable connection of the lid and box enclosure air filters for motor vehicles, developed and used by the manufacturing concern MANN + HUMMEL, for which air filtration only one part of a broad portfolio of filtration systems for the automotive industry in the world scale. Another part of this thesis will be one of the chosen optimization methods of connection and implementation of alternative proposals design solutions, including the selection of the best solution, creating design calculation, 3D design, FEA analysis and prototyping of an alternative connection method laser sintering. When creating the optimization and design of alternative design solutions can count on the possibility that existing solutions are taking all possible factors and that the best alternative design proposals show an improvement over existing at the expense of all other cells throughout the development of the product.
