Comparison of CAD programs
BARTOŇ, Petr
My thesis focuses in the first section on product lifecycle management (PLM), CA procedures and explanation of definitions used. In the second part the history is men-tioned and the third describes basic sorting of CAD systems. The most voluminous fourth chapter is dedicted to description of particular systems with their pros and cons and user environment. In the fifth part there are set the conditions of posibility of appli-cation based on interviews with constructers. The CAD programms are usually not che-ap anf for this reason they must meet the criteria of daily use optimally.

Calculation of temperature fields in induction machines
Horálek, Lukáš ; Dostál, Lukáš (referee) ; Janda, Marcel (advisor)
The issue of this thesis deals with the thermals electrical machines. Specifically, the calculation of temperature fields using the finite element method and analytical calculation of one of the machines with a replacement thermal circuit. Using Autodesk Inventor create a 3D model of the real electric machine and then in the ANSYS Workbench perform thermal analysis using finite element method. Next, perform analytical calculation of one part of the machine, namely the stator, using a simplified thermal replacement scheme. Also, we realize the measurement of temperature on the specific machine under various operating conditions, the calculations and measurements between them compared.

Camera Positioning Device
Berčík, Vojtěch ; Toman, Marek (referee) ; Červinka, Dalibor (advisor)
This master’s thesis deals with the design of a drive for a camera positioning device that could be used for shooting videos and timelapses. The optimal drive and power supply as well as the steering program based on the Arduino platform program are developed. The construction prototype adapted for printing at 3D printers is also designed. The whole system is then produced and tested.

Optimization of Cooling Synchronous Machine
Makki, Zbyněk ; Rafajdus,, Pavol (referee) ; Kačor,, Pavol (referee) ; Janda, Marcel (advisor)
The main goal of doctoral thesis is optimization cooling of the synchronous machine. Problem is solved based on the finite element method with use of ANSYS software. Work is built up from theoretical part where is comparison of base equations for heat transfer and simulations for several models. Next part shows us two methods how simulate free and force convection. Depends on the better method from the previous two methods is used for next calculations with several algorithm which are used for find of best parameters for synchronous machine. Our control parameter is mass flow rate.

The use of optical methods in the diagnosis of electrical machines
Tobolák, Petr ; Kuchyňková, Hana (referee) ; Janda, Marcel (advisor)
This term describes questions of scanning rotors of asynchronous motors using 3D scanner. At the beginning it deals with a theory of asynchronous motors, defects of these machines and last but not least also questions of 3D scanning. Directly it focuses on a practical processing of measured rotors and their necessary modifications using of a program GEOMAGIC. It includes a diagnostic of deviations of scanning components of rotors with a model created on a program AUTODESK INVENTOR and posiible reasons of their creation.

Experimental biomechanical hand prosthesis
Lux, Martin ; Rosický, Jiří (referee) ; Paloušek, David (advisor)
This masters thesis deals with experimental biomechanical hand prosthesis designing and its realization in shape of prototype. Hand prosthesis sizing corresponds with adult man hand. Prosthesis functionality is selected with respect to search analysis results, to provide sufficient options to grip different objects. Hand design, including technical documentation, is completely made in Autodesk Inventor 2012. Main parts of prototype are made with using rapid - prototyping technologies. Used materials for parts made by this way are ABS plastics and plaster powder. Firgelli linear actuators (product line L) are used as drive for electrical controlled fingers. Prototype control is realized by PCI card and program, which has been written in LabView.

CAD systems and design documentation
Kučera, Jaroslav ; Veselka, František (referee) ; Kuchyňková, Hana (advisor)
Project is specialized to work on modern CAD systems. Introduction treats of the development technical drawing and separates it into periods. There are compared two programs from Autodesk – AutoCAD a Inventor in the next part. Program Autodesk Inventor 2008 Suite is shown in more detail and project show innovations in this program compared to last versions. Work on Autodesk Inventor is shown at production of model of elementary electrotechnic equipment, technical documentation and presentation. This model, engineering drawings and presentation are the part of enclosure project. In end of project is attempt at the look to future of technical drawing.
