Calculation of storage tank structure for sewage treatment plant
Pečenka, Lukáš ; Maňas, Pavel (referee) ; Prokeš, František (advisor)
This diploma thesis is focused on finite element analysis of storage tank. The designed computational model in this work is based on existing storage tank documentation. Diploma thesis is divided into parts. Introduction part consists of various storage tanks types description and basis of finite element method. Next part contains methodical process of computational model designs, its characteristics and purpose. Designed models are loaded with set of specific border conditions. These tests are evaluated and described more closely. After that, the table of results is created and von Misses stress of all models is compared. The best model matching real construction is selected after this compare. The final part of this work consists of suggested construction changes based on the analysis results.

Mixing and kneading machine
Kopáček, Petr ; Anderle, Martin (referee) ; Prokeš, František (advisor)
This diploma work deals with design of the mixing and kneading machine which works with heated mixed components. The components consist of PET, HDPE, silica sand and additives. First, there is introduced knowledge from accessible sources, which are concerned with the theme. Then follows projection of variants and selection of suitable solution. With the help of obtained konwledge and the chosen variant is performed design proces. In the end is created a concept assemble of the machine. The design proces includes projecting of the individual parts, strength verification of the basic elements and design of heating device.

Small snow cutters
Ráheľ, Dušan ; Prokeš, František (referee) ; Brandejs, Jan (advisor)
The bachelor thesis deals with the subject of snowblowers. It describes their origin, evolution a current applications. It presents development and technical details of all snowblower sizes, ranging from smallest ones, driven manually by operating personal, to the largest, attached to the trains. The work explains modern hybrid snowblower powertrain. The combination of gasoline and electric engine proves to achieve substantial reduction of fuel consumption at unaffected efficacy of snow removal. The second part of work deals with our proposed novel method of snow removal, which employs its volume compression. A series of experiments were done in order to establish the relation between the exerted force and resulted compression of snow of various initial mass density. We have found that pressure smaller than 0,5 MPa is capable in average to reduce the snow volume to 45% of the initial value.

Positioning table for 3D optical profiler.
Kuruc, Marek ; Prokeš, František (referee) ; Šperka, Petr (advisor)
This Bachelor thesis deals with design and technical elaboration of positioning table for a 3D optical profiler, which is supposed to enable linear translation in two axes and tilting in two identical axes. Research of contemporary available solutions is made. Design priorities are precision of translation and tilt adjustment and achieving as low structure as possible.
