Traveling Crab 360 t
Sláma, Ondřej ; Kubín, Martin (referee) ; Pokorný, Přemysl (advisor)
The topic of this diploma thesis is the frame of the foundry crane with load capacity 360 t. The frame is analysed by strength inspection and fatigue strength inspection according to norm ČSN EN 13001. The analysis are made by using finite element method on shell model. The diploma thesis was made in cooperation with Královopolská a.s. company.
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.
Frame of foundry trolley crane 330 t
Otevřel, Marek ; Kolář, Pavel (referee) ; Pokorný, Přemysl (advisor)
The topic of this diploma thesis is the frame of the foundry trolley crane 330/65/20t. The crane crab is used for handling with molten metal. The frame is analyzed by strength inspection and fatigue strength inspection. The process is according to ČSN EN 13001. The analyses are made by using finite element method on a beam and shell models. The diploma thesis was made in cooperation with the Královopolská a.s. company.
Analysis of crab frame of bridge magnet crane 15t 27,5m
Strommer, Bohumír ; Kolář, Pavel (referee) ; Pokorný, Přemysl (advisor)
The diploma thesis deals with crab frame of bridge magnet crane with lifting capacity 15t used in steel mill for handling billets. Thesis contains strength analysis and fatigue strength check of crab frame based on ČSN EN 13001. Strength analyses are made by using beam and shell models of finite element method. The diploma thesis was carried out in cooperation with Královopolská a.s. company.
Linear buckling analysis of a flue gas pipe
Jančík, Jan ; Klučka, Ivan (referee) ; Naď, Martin (advisor)
The diploma thesis deals with the loss of stability of thin-walled flue pipe at coal power plant. The problem of thin-walled structures is their propensity to the loss of stability due to abnormal conditions, for example a vacuum, effect of wind, snow and earthquake. The purpose is to find the optimal deployment of reinforcements so that the model meets the requirements of EN 1993-1-6. This required an evaluation of unreinforced version of the model to identify weaknesses and subsequently other configurations for the application of reinforcement. For determining the resistance the flue pipe to the loss of stability used primarily to access linear bifurcation analysis based on linear analysis, possibly materially nonlinear analysis. The result of work is a design of reinforcement of pipeline which under the requirements of the standard meets the latest model with a reserve of approximately 20 %.
Static analysis of railway bridge
Bureš, Vojtěch ; Martinásek, Josef (referee) ; Vlk, Zbyněk (advisor)
The bachelor thesis deals with the static analysis of a railway bridge. Using AxisVM X6 software, I created 4 different models and compared them not only with each other, but also with simple manual calculations. Two models are beam models, the third is shell model, the fourth is also shell but with an end ledge that reinforces the entire structure. The structures are loaded by a manually calculated load according to the standard.
Fatigue evaluation methods for pressure equipment utilising numerical analysis results
Boleloucký, Václav ; Lošák, Pavel (referee) ; Létal, Tomáš (advisor)
Diplomová práce se zabývá hodnocením únavové životnosti v okolí konstručního uzlu tlakové nádoby, kde vzniká výrazná koncentrace napětí a je zde předpoklad primárního vlivu na únavu materiálu. Konkrétně se jedná o místo přechodu kontrolního otvoru do pláště analyzovaného zařízení. Práce obsahuje teoretickou a praktickou část. V teoretické části jsou představeny pojmy a metody hodnocení, související s danou problematikou. Na základě těchto metod je provedena analýza konstrukčního uzlu tlakové nádoby. Analýza je provedena metodou konečných prvků na skořepinovém a objemovém modelu nádoby v softwaru ANSYS Workbench, její výsledky dále zpracovány a vyhodnoceny dle aktuálního návrhu úpravy evropské harmonizované normy EN 13445--3, kapitoly 18. Výsledky analýz jsou hodnoceny v závěru práce.
The assessment slender bridge structure subjected to dynamic loads and design of the damping devices
Řehová, Jana ; Hradil, Petr (referee) ; Salajka, Vlastislav (advisor)
This master thesis deals with the dynamic analysis of a footbridge. Computational model of the footbridge was created using ANSYS software. The model was subjected to dynamic wind load in longitudal and lateral direction. Furthermore pedestrian load in lateral direction was analyzed. Afterwards, due to unsatisfactory response to the pedestrian laod, a tuned mass damper was introduced to reduce the vibration. This lead to decrease in the vibration to a satisfactory levels, as is shown in the analyses of the model.
