Creation and analysis of electrical machines parametric models at CAD systems.
Chmelíček, Petr ; Janda, Marcel (referee) ; Kuchyňková, Hana (advisor)
Aim of this bachelor’s thesis is to demonstrate facilities of computer aided design on practical tasks. First part contains description of Autodesk Inventor, which is one of the most important modern parametric CAD systems. There is described the basics of modeling, drawing creating and analysis of design. Second part is oriented on demonstration of capabilities of Ansys Workbench, which is important system for solution of engineering problems by the finite element method. Also there is description of user interface of Ansys, analysis of electromagnetic field in asynchronous motor and description of one phase asynchronous motor. Task of last part is to create animated presentation of asynchronous motor with outer rotor in Inventor studio.

Numerical Modelling of the Gear Mesh Stiffness
Gazda, Silvester ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
This master's thesis deals with the design of FEM model of gear pair with an intention to find out how stiffness changes during meshing. It firstly describes the necessary knowledge needed to analyse the problem, like the geometry of an involute tooth and evaluation of meshing stiffness. Followed by a description of work procedures from the creation of models through settings of mesh, contacts and analysis to evaluating of results.

Design of high speed induction motor 350kW, 40000r.p.m.
Karásek, Ladislav ; Vítek, Ondřej (referee) ; Ondrůšek, Čestmír (advisor)
This thesis deals with the problem of the high-speed electrical machines. In the introduction summary of the high-speed machines are discussed. Induction machine with squirrel cage winding and solid rotor is chosen as suitable solution for given requirements. The multiple types of designs of the induction machines with solid rotor and problematic areas are discussed. Main part of this thesis is an electromagnetic design of the machine with respect to mechanical stress. The designed machine is analyzed with the use of finite element method in ANSYS Mechanical and Maxwell software.

Static analysis of arch bridge structure
Farkasová, Zuzana ; Zídek,, Rostislav (referee) ; Hradil, Petr (advisor)
The main task of the Bachelor´s thesis is to do a static analysis of arch bridge construction with two span and bridge deck hanged on pulled cables. My task was to construct numerical model of bridge construction, to make load solution and to evaluate results. I have learned about ANSYS programme during processing this thesis, especially about its working environment WORKBENCH.

Utilization of ANSYS Workbench program at power electrical engineering
Partl, Tomáš ; Aubrecht, Vladimír (referee) ; Kuchyňková, Hana (advisor)
In its first part this Master´s thesis describes creation of electronic database design in Raster Design 2009 program as an effective form of storage only for paper documentation. The second part of my thesis provides calculation of primary and secondary winding of current instrument transformer of over-current conduit through the winding and influence on other parts of transformer i.e. error of transformer or increasing magnetic induction core and others. The last third part is focusing on usage of ANSYS Workbench in power electrical engineering. The thesis shows specific example of warming of current instrument transformer (thermal analysis) and comparing the results with theoretical (calculated) values.

High Cycle Fatigue Modelling in ANSYS Workbench
Zoubek, Vojtěch ; Řehák, Kamil (referee) ; Dlugoš, Jozef (advisor)
This diploma thesis deals with the extension of the solution of high-cycle material fatigue in Ansys program. The goal of the thesis is creation own algorithm for evaluation of FEA results and overcoming the existing built-in tool. Thesis is divided into theoretical and practical part. In theoretical part, there was created literary research about material fatigue and current solution options. Practical part introduces own algorithm of evaluation.
