Production logistics
Olej, Tomáš ; Vaněk, Jiří (referee) ; Špinka, Jiří (advisor)
This master’s thesis deals with manufacturing and logistic issues of low voltage cabinets produced by ProCS, s.r.o. company. The aim is to design and evaluate manufacturing and assembling process rationalization proposal. The proposal is based on familiarization with technological process of cabinet's manufacturing. Becoming familiar with manufacturing and assembling process of marshalling and system cabinets made it possible to find an opportunity of rationalization through automation of selected assembling processes. Automation of striping and crimping process is possible through suitable crimping machine. Situation before and after rationalization is economically interpreted and evaluated using break even point analysis. Through mentioned rationalization arrangement it is possible to improve manufacturing flexibility, reduce lead times and cut down manufacturing costs.

Sandwich panels analysis under compressive load using finite elements methods
Seman, Matúš ; Löffelmann, František (referee) ; Mališ, Michal (advisor)
Bachelor thesis deals with possibilities of numerical modeling failure mechanism in sandwich panels using final element methods. The first part of the thesis presents theoretical introduction to requirements of sandwich structures and either mathematic formulation of constitutive relations. The purpose of the thesis was to set suitable approcahes of formulation instability problems with applying on laboratory samples. The analysis was done using nonlinear solvers in programes Patran/Nastran and the results have been properly evaluated with experimental work and analytical approach.

Analysis of a Sandwich panel under compressive loading
Kopylov, Gleb ; Katrňák, Tomáš (referee) ; Mališ, Michal (advisor)
Hlavným cieľom tejto bakalárskej práce bolo navrhnúť vhodnú simulačnú metódu pre rovinnú šmykovú skúšku. Boli popísané rôzne typy porúch kompozitových panelov a rôzne prístupy k šmykovým skúškam. Boli navrhnute rôzne simulačne metódy pre jednoosú šmykovú skúšku. Na základe najdôležitejších kritérií, bol zvolený najvhodnejší návrh. Šesť experimentov bolo nasimulovaných v súlade zo zvoleným návrhom. Výsledky simulácii a výpočtov boli porovnané pre utvorenie korelácie medzi hodnotami a overenia správnosti simulačného návrhu. Na základe daného porovnania, takisto boli zistene skutočnosti ohľadom wrinkling kvocientov a platnosti rovníc pre výpočet crimpingu.

Quality evaluation of the connection of low-voltage control circuit cables
Chabiniok, Pavel ; Prostredník, Daniel (referee) ; Jankových, Róbert (advisor)
This master’s thesis deals with evaluation of quality of the connection of low-voltage control circuit cables, with the emphasis on quality assurance of crimps. An analysis of possible quality control methods, including a map of the crimping process, was created. Further, the thesis includes proposals for improvement of the original system. Furthermore, a proposal of non-destructive inspection system was produced. The conclusion summarizes the knowledge gained in quality control of crimping, including practical recommendations.
