Design of container for bulk transport
Cihlář, Milan ; Lošák, Pavel (referee) ; Létal, Tomáš (advisor)
The topic of this work is industrial usage of ISO containers and their classify. Other part is about construction a stress analyses of container type 1C (length is 20 feet) which is used to a bulk transport. The software Ansys was used to stress analyses. In this analyses was used only simply model which don´t have filling and emptying aperture etc. In results was controlled maximum stress in the all elements.

Nonlinear buckling analysis of a flue gas pipe
Jelínek, Jan ; Vincour, Dušan (referee) ; Létal, Tomáš (advisor)
This thesis deals with the nonlinear analysis of stability loss of flue gas pipe. This pipe is a part of desulphurization line. The thesis describes the creating of a simplified FEM model. It also describes the setting of the boundary conditions of the model for few loading cases. These cases differ by preference for one of the load as dominant. There are proposed several variants of stiffening by light ring stiffener. The work is finished by comparing the resistance to the stability loss of the reinforced variants and unreinforced model of flue gas pipe.

Modelling of pressure equipment bolted flange connections
Kolátor, Matyáš ; Pernica, Marek (referee) ; Létal, Tomáš (advisor)
The bachelor thesis deals with computational modeling of flange connections. Due to its separability, bolted flange connections are a frequently used in piping systems or pressure vessels. For the right functionality of the connection, it is necessary to ensure the required tightness. In order to be able to describe the tightness, it is necessary to know the stresses and deformations in all parts of the connection. These days, standard calculation methods are at a high level of accuracy, on the other hand, in order to achieve this accuracy, they have to follow a lot of corrections, in which the original model based on the strength of material theory should be lost. The aim of bachelor thesis is to create computational models based on the strength of materials theory. Computational models are created to illustrate the application of strength of materials theory. At the end of the thesis, the results using several models will be summarized and compared.

Principles and design of project elaboration of boiler islands aimed at piping
Suchomel, Radoslav ; Létal, Tomáš (referee) ; Nekvasil, Richard (advisor)
The Thesis solves the issue of a design and construction of piping specifically focused on boiler apparatus and its equipment. This issue is important for creation of the piping classes in the (PDMS) programmes and for acceleration of output parameters which are mainly the temperature, materials, variable parameters, etc. This leads to other problems such as service life, security, economy, etc., are.

Software Aided Design and Assessment of Shell and Tube Heat Exchangers
Létal, Tomáš ; Klemeš,, Jiří (referee) ; Vincour, Dušan (referee) ; Jegla, Zdeněk (advisor)
Subject of this work is a development of an integrated software environment for mechanical design and check of shell and tube heat exchangers. Processes of mechanical design and checks well as software which perform these processes are broken down to basic methods and parts. Mechanical design is usually performed according to some standards. In this work, ČSN EN 13445 is used. This standard describes mostly design check calculations which can be easily algorithmized. On the contrary, design calculations are described to some extent in few simple cases and mechanical design of shell and tube heat exchanger has not been fully algorithmized yet. Subject of this work is design of software, which will be capable of automatically performing mechanical design from datasheet as an input. Based on breakdown of design and check processes, requirements for key software features are derived. Important part of presented work is design and implementation of key modules – data model of shell and tube heat exchanger, module for mechanical design check according to ČSN EN 13445. These modules form basis of the software which will be developed further in future work.

Design of storage tank
Nováček, Filip ; Létal, Tomáš (referee) ; Nekvasil, Richard (advisor)
The aim of this diploma thesis is to design of storage tank for petroleum. The thesis is divided into two parts. In the first part of the work is focused on introducing the known types of storage tanks, their parts, use and benefits. The thesis also briefly summarized legislation regarding this issue. The second part is the actual design of storage tank. It was the strength calculation tanks according to EN 14 015. It was also a voltage FEM analysis of shell and tank roof. Result of work is a design drawing of the storage tank.

Pressure vessels loaded by external pressure
Paták, Roman ; Létal, Tomáš (referee) ; Lošák, Pavel (advisor)
This final thesis addresses the approach of standards and software for calculation of pressure vessels loaded by external pressure and a design of own calculation software, including a demonstration on chosen geometry. The approaches of standards and software are solved in the form of research. The practical part describes the developed software, selected technologies for development and results of the demonstration. The demonstration was carried out on two geometries and was successful.

Design of autoclave
Poduška, Libor ; Létal, Tomáš (referee) ; Nekvasil, Richard (advisor)
Master thesis deals with general basic design od autoclaves. It deals with the design of an optimal design solution autoclave to set parameters with the design requirement of hermetic doors for loading the workpiece. This solution is analyzed regard to stable pressure vessels. The whole design is processed in parametric SolidWorks software with which they are executed and initial stress analysis of individual designs. Final strength FEM analysis is performed using Ansys. Some proposals are technical-economic evaluation.

Thermal-hydraulic calculation and stress analysis of a heat exchanger
Fiala, Petr ; Létal, Tomáš (referee) ; Nekvasil, Richard (advisor)
Main object of the work is stress analysis of specific parts of tube and shell heat exchanger by using MKP. Each part is judged by two different computation methods. The method based on computation values and the method nearing real condition of operation of device. To approach real load are in the work made basic heat transfer computations for entire device and for analyzed part are computed boundary conductance by using CFD.

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.
