Mechanical analysis of the front wipers mechanism of a Škoda car
Košinová, Laura ; Hájek, Petr (referee) ; Fuis, Vladimír (advisor)
This bachelor’s thesis deals with the mechanical analysis of the front wipers mechanism of a Škoda Felicia and Škoda Octavia cars. Firstly, the explanation of necessary terms of mechanics needed for the solution to the problem is provided, followed by a brief history of windshield wipers. The aim of the practical part was to find the driving moment and contact forces in the links and further analyze the behavior of the mechanism after overcoming the static stability limit. The creation of mechanism models in Solidworks was also included. The unknown parameters were determined using Matlab. The dynamic analysis was solved numerically using Ansys software.

Návrh autonomní robotické kolové platformy
LARVA, Jaroslav
The diploma thesis represents the project of design and implementation of an autonomous robotic platform, which is built on the basis of a modified children's buggy, enabling its remote control. The entire project is systematically divided into two basic parts: theoretical and practical. In the theoretical part, the components and software tools used during the project are analyzed in detail. This section provides an overview of current trends in robotics and autonomous systems and highlights the importance of each selected element to the success of the overall design. In the practical part, the work focuses on the development process itself. From the first steps in construction, through the programming of the purchased platform, to a detailed description of the connection and integration of electronic components. Specific attention is paid to technical solutions that overcome the challenges associated with adapting a children's buggy to an autonomous robotic platform. In the final part, the project is evaluated as a whole. It includes an analysis of the achieved results, reflection on possible areas of improvement and discussion of future directions of development.

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.

Analysis of Whirling of Gas Flow within the Specimen Chamber of ESEM
Bayer, Robert
The usage of an Environmental scanning electron microscope (ESEM) brings the possibility of studying many kinds of materials and chemical reactions never studied before. In this article there are compared and analyzed several simulation results of gas flow in the specimen chamber of ESEM with high gas pressure throughout the whole volume except on its optical axis, where low gas pressure is needed.

The effect of the shape of the intake ports for pumping in a Scintillation detector.
Flídr, Karel ; Vyroubal, Petr (referee) ; Maxa, Jiří (advisor)
The thesis is concerned with the design of the shape of suction canals used for pumping in the scintillation detector. The goal is to perform analysis of the model of the detector according to the current conception and then perform an optimalisation of the suction canals as per demands to their function. In the beginning of the thesis the history of the microscope and electron microscopy is described. The next chapter is focused on a more detailed description of ESEM. The following charter is dedicated to describing the scintillation detector.The thesis recounts the kinds of liquid flow. In conclusion the programs SolidWorks and Ansys Fleunt are described. Next part of this thesis describes in detail parameters‘ settings of simulation calculation. Following chapter introduces designed changes of suction channels shape and its results are shown and described.

Manufacturing of Components Using Rapid Prototyping
Peňáz, Jan ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis deals with solution of manufacturing prototype using three technologies. Two of them are additive technologies using principles of Laminated object manufacturing and Fused deposition modelling. The third technology was milling. Model of reversible turbine was used as a base for manufacturing. CAD system SolidWorks was used for the model creation, where output formats were SLDPRT and STL. For error check of STL data software MiniMagics was used. For preparation of 3D printing data softwares SD View and Catalyst EX were used. CAM system SolidCAM was used for creation of machining strategy. Devices used for manufacturing of prototypes were 3D printer Solido SD 300 Pro, 3D printer Stratasys uPrint and 5axis mill Hermle C20U. Print on 3D printer Stratasys uPrint the most advantageous technology for manufacturing one prototype.
