Optimization of SLM process for manufacturing of assault rifle muzzle device
Kubrický, Jakub ; Majzlík, Pavel (referee) ; Vtípil, Jaroslav (advisor)
The thesis deals with optimization of the manufacturing process of the muzzle device designed for assault rifle. The most common titanium alloy named Ti-6Al-4V was chosen for this task. The introduction summarizes previously existing types of muzzle devices and further describes the SLM technology with a special focus on titanium alloys processing. The optimization methods and their follow-up testing were designed according to theoretical knowledge that is summarized in the theoretical part of this work. Firstly, the aim was to describe the optimization of the manufacturing process with attention to preserving the relative density of the parts. Secondly, the mechanical properties of the parts that underwent different heat treatment were tested.The obtained data were then used to design and manufacture a muzzle device that underwent further testing in real condition afterwards.

Design of heating system for apartment building
Vtípil, Jan ; Horká, Lucie (referee) ; Vyhlídalová, Karolína (advisor)
The bachelor's thesis deals with the design of heating and water heating in a smaller apartment building in the village of Chlumětín in the Vysočina region. The aim is to design heat sources in two variants. The first variant is the classic heating with a gas boiler and hot water heating in the storage tank, which is heated by the same boiler. The second variant is more environmentally friendly heating using two air / water heat pumps and hot water heating is solved using solar collectors.

Universal muzzle device for an assault rifle
Rušar, Filip ; Majzlík, Pavel (referee) ; Vtípil, Jaroslav (advisor)
This diploma thesis deals with the design of a universal muzzle device for the assault rifle. The device is designed to produce Selective Laser Melting. The main objective is the elimination negative effects of gunshot. The paper explores possibilities of using porous structures for this type of equipment. The influence of individual types of porous structures on the flow of gases is monitored. The universal muzzle device itself is optimized using CFD analyzes. The device was made using SLM technology and experimentally verified. His impact on the impact, gun lift, noise and flame elimination was investigated.

Low-energy building of boarding house in Chlumětín
Vtípil, Jan ; Blasinski, Petr (referee) ; Počinková, Marcela (advisor)
The master thesis deals with the design of environment friendly boarding house, which is located on a hill in a small village called Chlumětín. There are designed renewable energy sources, such as solar collectors or fotovoltaic panels. The first part deals with the design and layout of the boarding house. On the ground floor is solved, the design of the kitchen according to hygienic requirements, the design of the premises for guests with barrier-free toilets. In the attic are designed guest rooms including barrier-free room. The second part deals with the simplified design of building services. It includes rainwater management, mechanical ventilation with heat recovery, lighting, cooling and heating. The third part deals with the detailed design of heating in the building. It includes design of radiator power, pipe dimension, power of wood-gas boiler, storage tanks, pumps, etc.

Explicit dynamic finite element analysis of a firing pin assembly
Mochar, Dominik ; Gabriel, Dušan ; Masák, Jan ; Kopačka, Ján ; Kolman, Radek ; Plešek, Jiří ; Hynek, P. ; Vtípil, J.
In this paper, explicit dynamic finite element analysis of a firing pin assembly was performed. Two different geometries of the firing pin were considered using the finite element software PMD and Abaqus. For both variants there was evaluated a stress distribution at the critical point of a tested component, that is going to be later used for a fatigue analysis of the firing pin.
