Stress analysis of the total hip joint endoprosthesis head under oblique loading
Janovský, Martin ; Janíček, Přemysl (referee) ; Fuis, Vladimír (advisor)
This diploma thesis is concerned with the stress analysis of the total hip joint endoprosthesis ceramic head under oblique loading. Load was obtain from experimental in vivo measurement on three patients, whereas two of them was the same weight. As input variables were use contact forces, especially knee bend and standing on one leg. Furthermore they will be considered shape deflections from ideal cone, especially circle deviation, cone deviation and cone plus circle deviation together.

Bucket-wheel boom of stacker/reclaimer
Štursa, Martin ; Krása, Jakub (referee) ; Pokorný, Přemysl (advisor)
This master’s thesis deals with the construction of parts of a bucket-wheel stacker/reclaimer designed to operate lignite stockyard at coal power plant. First the basic parameters of machine and loads applied in service are defined. The work also includes the design of steel structure of bucket-wheel boom, bucket-wheel, buckets, bucket-wheel drive, shaft, bearings and other parts of bucket-wheel boom. These parts are verified by analytical or finite element analysis.

Design of tank container for storage of petroleum products
Bezděk, Lukáš ; Nekvasil, Richard (referee) ; Létal, Tomáš (advisor)
This diploma thesis presents design of oil storage container type ISO 1CC. The container is designed according to ISO standards. The standards prescribe or limit some of the container dimensions, other dimensions are derived from specific purpose of the container. The container can be considered either as a transport container (empty) or as a stationary tank (full). Therefore, the load conditions are given by ISO for transport containers in the first case and by ČSN EN for the latter. The goal is to design and evaluate various container designs by FEM (finite-element method) analysis.

The stress analysis and design optimizing of the trailer MEGA 25
Halama, Tadeáš ; Molva, Martin (referee) ; Kašpárek, Jaroslav (advisor)
This Diploma Thesis is dedicated to stress analysis of carrier swap bodies Mega 25 with maximum technical weight 27 000 kg and has been worked out in corporation with ZDT Nové Veselí company. The aim of this work is to stress analysis of trailer in various burdensome conditions. The first section of the Thesis is occupied with original design and burdensome condition. Then, according to these states gained strength to control the finite element method, implement and then modify the design including design of new drawbar and then create selected construction drawings prepared.

The analysis of frame synchronous generator
Marada, Ondřej ; Střelková, Radka (referee) ; Pokorný, Přemysl (advisor)
The thesis is focused on the examination of the utility of a synchronous generator of a small hydroelectric power station in the case of a change of working position of the machine. The utility will be measured on the basis of the examination of deformations and state of stress of the frame of the generator for the present running (with vertical axis of rotation of the generator) and subsequently for modified running (with horizontal axis of rotation). This will be accomplished partly on the static shell model by finite element method and consequently on the simplified dynamic model.

Solid Edge - Design of Omnidirectional Mobile Robot Platform
Poul, Ota ; Šoustek, Petr (referee) ; Matoušek, Radomil (advisor)
The bachelor thesis deals with design of three and four wheeled omnidirectional mobile robot platform. Design of both platforms is created in CAD software Solid Edge ST4. The result of this work are 3D models of mobile robot platforms for drawing documen-tation and subsequent realisation of platforms using predefined motor units. For both variants of the platform a stress simulation and visualisation were created within the possibilities of applied software.

Placement Optimization of Projector Lens
Bezděk, Matěj ; Važík, Jiří (referee) ; Novotný, Pavel (advisor)
This diploma thesis deals with the creation of engineering design of holder of projector lens. The thesis is created in cooperation with department of development in Varroc Lighting Systems, s.r.o. Initial part provides a brief description of the development of lighting technology used in car´s headlamps. The following part describes solutions currently used in clamping the lens in holder. The main part of the thesis focuses on the design of holder of projector lens itself. Projector lenses testing provide critical values of cohesive failure of the lens material, which cannot be exceed during the process of lens fitting and its subsequent clamping. In the final part the engineering design is verified and optimized using finite element analysis.

Stress analysis in parametric FEM programs
Martinec, Roman ; Vlach, Radek (referee) ; Krejčí, Petr (advisor)
The bachelor thesis focuses on familiarizing with Autodesk Inventor Professional 2012 program and ANSYS Workbench program. It was necessary to get familiarized with working environment of these programs and their mutual cooperation. The interconnection between the two programs is described on a demonstrative case. Next article of the thesis deals with a model conversion into MKP software which was described in detail within both programs. The final part of the thesis compares the results of a stress analysis within Autodesk Inventor Professional 2012 program and also within ANSYS Workbench.

Design of separator
Benda, David ; Nekvasil, Richard (referee) ; Lošák, Petr (advisor)
This diploma thesis deals with design of the gas separator according to the standard ČSN EN 13445. The design is based on the specified operating parameters and the basic dimensions, including the individual positions of the connecting flanges on the device according to the relevant schema. The assignment also includes the load of the nozzles from connected pipelines to the device. The analytical calculation of the design is performed in the commercial software NextGen with the analysis of the individual components used. Furthermore, some parts of the device are inspected in detail using the finite element method in the commercial software Ansys. The thesis also included the drawing documentation of the designed gas separator.
