Modern trends in the design of frame machine
Holík, Štěpán ; Urbánek, Michal (referee) ; Zeizinger, Lukáš (advisor)
The bachelor's thesis deals with the issue of using modern methods of machine structures design, especially topological optimization. The first part describes the history of design, design methods in terms of approach to the technical problem and product development process. The second part discusses the various methods used in the design. The methods of topological optimization are compared and software solutions that enable topological optimization are described in detail. The fourth part deals with the dimensioning of components using topological optimization with a demonstration of important details on a specific example in Ansys Mechanical and MSC Apex Generative Design.

Experimental Verification of Optimal Shape of Beam
Uríček, Matúš ; Keršner, Zbyněk (referee) ; Frantík, Petr (advisor)
The thesis deals with design of beams of optimized shapes, which are than manufactured by 3D printer and their features are experimentally verified. When the limit strength of a given component is reached, ways of fracture development are observed. Information obtained from the experiments are then compared with assumptions generated by numerical methods.

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.

Design study of the heat switch base plate with single and multi-material topology optimization
Löffelmann, František ; Šplíchal, Jan
A miniaturized heat switch is a device under the development dedicated to control automatic cooling of a space instrument box. The design study presented in this paper focuses on a stiffness issue of the switch base plate which should assure good thermal contact with the instrument box. Due to inner deformations of the switch, base plate deforms which might decrease contact area needed to the heat transfer. Thus several design concepts of the copper base plate were investigated and multi-material additive manufacturing was reviewed. One approach was to decrease deformations of existing geometry by multi-material design by local exchange of copper with steel, first by engineering intuition, then by the stiffness based topology optimization, and finally with the layer-wise topology optimization better respecting manufacturing possibilities. Another approach was to change the geometry and use the topology optimization constrained with a flatness of the base plate but with single material. Finally, deformation changes of all the variants were compared.
