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 of the portable veterinary X-ray machine
Kalenský, Ondřej ; Surman, Martin (referee) ; Škaroupka, David (advisor)
This diploma thesis is focused on the design of a product family of portable veterinary x-ray generators. The thesis deals with the possibilities of using parameterization when designing products which are part of a product series. The main body of the thesis lies in the design of a parametric script which generates variations of portable veterinary x-ray generators depending on the size and position of the inner components. The outer surfaces are defined by algorithms from the input parameters. It is possible to alter the individual attributes (e.g. the progresion of curves, the dimensions of component parts and the proportions between the individual parts). The output from the parametric script is three size-variations of the product.

Design of the hammer set
Král, Ondřej ; Haltof, Vladimír (referee) ; Škaroupka, David (advisor)
This bachelor’s thesis is focused on the design of a product family of hammers by the means of generative design. The core of this thesis is the creation of an algorithm which will generate hammers of unified visual style, but varying properties based on input parameters. It is necessary that these hammers are in shape, ergonomics and dimensions adequate to preferences of the target group of professional workers and that they are producible in series and from commonly used materials. The output is a set of three hammers with different mass and dimensional properties.

Jaroslavice – place in the landscape
Šmejkal, Jiří ; Galeová, Nicol (referee) ; Ponešová, Barbora (advisor)
The theme of this diploma thesis is the architectural study of the complex of the Farm of 3D Printers in Jaroslavice. The technology of 3D printing at its speed of development has far outweighed the response to its needs. It lacks a new systematically planned building typology corresponding to the requirements of farms. Farms adapt to the spaces. The main aim of the work is to introduce the possibility of turning the situation and adapting the premises to the farms. The thesis follows the urban design of the restructuring of the Jaroslavice landscape elaborated in the previous semester. The project respects established principles at microregion level in the form of emphasis on self-sufficiency, population integrity or the use of current technologies. The land is located on the southern part of Jaroslavice. There are 3 agricultural buildings located on the property, which until 2010, when a photovoltaic power plant was built, operated in conjunction with a neighboring agricultural court. After the power plant was built, the bonds were irreversibly broken. Buildings are in a very poor condition and mutual cooperation no longer works. The existing solution replaces and shows the possibility of using solar energy in a different way. Thus, the construction cartridge works with a hybrid typology where the 3D production area is combined with the maximum solar gains of the photovoltaic panels. Generative methods have been used to design dominantly either for finding a form in terms of achieving maximum solar gains or after verifying the efficiency of the structure. The proposal has several scenarios of possible development. There are four different stages of growth and the linkage of production areas. Printers are able to replicate themselves at such a rate that they can expect rapid growth. The proposal uses controlled growth methods to simulate complex development under the conditions of maximum solar radiation. Visual distraction and overheating are also solved by atypical sunsets on the exterior façade. Thin-film photovoltaic panels are used on the sun, so it is able to produce electricity besides the shield. The energy-efficient shape along with the great advantage of the layout solution, instead of the corridor disposition, is a basic cell on the central plan view. This makes it possible to control and operate more of the machines more efficiently. The production site forwards counts full robot automation.

GENERATIVE FURNITURE
Picek, Matěj ; Krejčí, Daniel (referee) ; Tobola, Ondřej (advisor)
This thesis deals with the basic principles of the functioning of the technology of generative design, using the method of topology optimization and finding their potential with the capabilities of the application in the field of furniture design. The main outcome is a functional prototype of a low relaxing chair, which specific construction is designed using the method of topology optimization.

Design and production of selected 3D printed metallic parts
Masson, Quentin ; Polzer, Aleš (referee) ; Píška, Miroslav (advisor)
Thales LAS France currently has parts of their system that are manufactured by forging or casting. Nowadays the tools and equipment for those processes are getting worn, the sub-contracting company in charge of some of casted parts can’t guarantee the quality of those parts anymore. Moreover, Thales recently has set up a plant specialized in metallic additive manufacturing and the policy of production is to encourage the production in that subsidiary. In order to adress those issues, Thales LAS France managed to prepare his design office for designing parts that will be 3D printed. My function is to establish a methodology for the mechanical design of parts that will be manufactured in additive manufacturing. Once the researches about the process and the different technologies will be done, I will establish steps that must be achieve for the mechanical design of a piece or a system. The methodology will take into account the physical properties that can be guaranteed by the process and their flaws such as the porosity for instance, the constraint linked to the technology and if possible apply to the part a topological optimization.
