The wrist joint for upper limb prosthesis
Hollein, Radek ; Komenda, Lukáš (referee) ; Paloušek, David (advisor)
This bachelor thesis deals with the structural design of the wrist prosthesis allowing positionability and lock and subsequent implementation of a functional prototype. The structural design is made to be innovative. With respect to the research, the range of movement and the number of positions of the locking mechanism are selected to ensure the functionality of the prosthetic wrist. The size of wrist prosthesis is designed for an adult male hand. For the structural design Autodesk Inventor Proffesional 2012 was used. Drawings were prepared using AutoCAD Mechanical 2012. Individual components of the prototype are made of ABS plastic, using rapid prototyping technology, or steel machining blanks.

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.

Production of the car gearbox using Fused Deposition Modeling method
Štěrba, Ondřej ; Nejedlý, Jindřich (referee) ; Sedlák, Josef (advisor)
The aim of this work is creating a virval model of the car gearbox . The gearbox from the car Skoda Felicia was used to create the individusl parts into a final assembly. Construction of the assembly model and the layout have been implemented inAutodesk Inventor, which is a software CAx application. Final production was performed by Rapid Prototyping Technology, using the Fused Deposition Modeling equipment uPrint from ABSplus material for the purpose of visualization. The final verification was assemblin single patrs of the gearbox, including ensurance its functionality.

Design of vibration energy harvester with blade joint
Beňo, Martin ; Hadaš, Zdeněk (referee) ; Rubeš, Ondřej (advisor)
This bachelor thesis deals with the design of vibration generator with blade joint. Firstly, its main aim is to design a working vibration generator, and secondly is to entice the reader to continue on with reading. Such a vibration generator is a handy, inexpensive to manufacture, and especially very simple. The basic design element of the vibration generator is oscillating frame connected to the blade joint and is the carrier of the magnets. The electrical part of the generator consists of a magnetic circuit and coil on the static bracket. Oscillating frame with magnet creates a changing magnetic field and induces voltage in the coil. For the design of the construction was used the program Inventor. For the calculation of the magnetic circuit has been selected, the program FEMM controlled by MATLAB. For the calculation of the static and the dynamic analysis was chosen the program ANSYS.

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.

Temperature measurement on electrical machines
Prezbruchý, Martin ; Skalka, Miroslav (referee) ; Mikulčík, Aleš (advisor)
This work is trying do describe the temperature allocation on the electric machines. In the first part it is describing the temperature measurment, principals of measuring, thermocouples and a contactless measurment. In the second part, it is theoretically proceeding with engine types and a heat generation on them. In the third part, the work is describing simulation in the programs Autodesk Inventor and Ansys Workbench. In the next part, a work is showing the creation of a elektric machine model in already mentioned programs and a practical measurements of temerature allocation in the laboratory. In the conclusion, it is evaluating the measurment achievements and comparing the results of both used metods.

Using optimization methods to design machine parts
Kubrický, Daniel ; Pokorný, Přemysl (referee) ; Zeizinger, Lukáš (advisor)
This bachelor thesis describes using structural optimization methods to design machine parts. In the first part of the thesis, a description of the current state of knowledge of the optimization process was made together with its theoretical background. In the second part of the thesis, a static analysis and topology optimization or Generative design was developed using the example of a bell crank in six commercial software. In the third part, the resulting models of each software were compared with each other, and the results were compared using the von Mises maximum stress criterion and the overall model deformation. Finally, this work was concluded with an evaluation of the use of the structural optimization software.

Elaboration of examples for teaching visualizations in Inventor
Hejl, Vojtěch ; Odehnal, Lukáš (referee) ; Košťál, David (advisor)
This bachelor’s thesis describes functions of Autodesk Inventor that deal with visualizations and the creation of excersises for students on this topic. For this purpose were created three powerpoint presentations describing the functions of this program concerning visualizations and methods of creating visualizations of objests. These excersises are comprised of a powerpoint presentation, model and textures. The ability to use visualization tools of Inventor is aplicable in marketing or design. It enables the creation of visualizations greatly resembling real life objects without the need to create these objects beforehand.
