Production of casting cylinder for engine modification of motorcycle Jawa 50
Chvátal, Pavel ; Pernica, Vítězslav (referee) ; Bořil, Petr (advisor)
Production of casting cylinder for engine modification of motorcycle Jawa 50. This bachelor thesis deals with the design of an air-cooled cylinder for racing modification of the JAWA 50 engine and its subsequent implementation using the rapid prototyping function. The designed part was cast and the finished casting was subjected to analysis.
Design of injection mold production technology for precision casting
Fendrich, Tomáš ; Polzer, Aleš (referee) ; Zlámal, Tomáš (advisor)
The diploma thesis deals with the design and production of an aluminum injection mold for investment casting. The work briefly describes the technology of investment casting together with a description of the types of molds, their internal arrangement and the most commonly used materials. Another part of the work is devoted to the analysis of aluminum molds machining. Emphasis was placed mainly on those operations, that will be used in production of mold. The practical part describes in detail the process of designing the model and mold, as well as the process of designing production technology. The construction is performed using the program SolidWorks, production technology using the program SolidCam. At the end of the work, the mold is assembled and the functionality of the mold is verified by means of test injection and economic evaluation is made.
Machining of vulcanizing molds from aluminum alloys
Kaška, Zdeněk ; Kalivoda, Milan (referee) ; Polzer, Aleš (advisor)
This diploma thesis is focused on the issue of deep drilling of vulcanization molds from various aluminum alloys. The work will describe a brief description of machined materials and tools for deep drilling, including the production of the vulcanization mold itself. Based on experimental measurements, the analysis of data and knowledge gained from deep drilling of aluminum alloys with different silicon contents will be performed. In the end, the individual components of force loads for both machined materials will be compared
Charakteristiky evropských veletržních areálů
Štěpánková, Lenka
Large exhibition centres in European cities represent a specific type of urban space with their own unique parameters. Whilst formal parameters deal with scale and form, functional parameters pertain mainly to logistics and the operating of the venue. In this paper, other important parameters are included with those already referenced. Financial parameters such as the total exhibition area available, total build up area and total venue area are combined. The results speak about a venues capacity or their spatial potential and can be used to predict the need for further transformation or relocation of the certain venue in the future.
A proposal and production of vacuum mold for serial production of plastic forming
Tišnovský, Jakub ; Chladil, Josef (referee) ; Sedlák, Josef (advisor)
This diploma thesis deals with the proposal and production of a mold for series production of plastic parts by vacuum forming. The thesis is divided into 2 main chapters. The theoretical part includes analysis of chip machining technology. The experimental part focuses on solving the design of the mold in PowerShape software, a detailed analysis of making of the model for casting and about making of the mold themselves. In the last part the manual completion and verification of the mold is discussed. Thesis is terminated by technical-economic evaluation, in which is discussed about production costs.
The current trends of outdoor advertisment extraordinary forms, focused on Prague
Linhart, Tomáš ; Klabíková Rábová, Tereza (advisor) ; Koudelková, Petra (referee)
This thesis addresses the complexity of outdoor advertisement in the Czech Republic. In the theoretical section, characteristics of outdoor communication, advantages and disadvantages, forms, the market and associations are presented. The empirical section analyses the current trends of outdoor advertisement extraordinary forms based on the field research findings and the concluding chapter puts both the theory and findings into the context of the environment in Prague. In this final part, the advertisement smog and accordance with surroundings and legislation are examined. The default assumption is that the outdoor advertisement is ubiquitous and is influencing every single individual. The impact varies, but essential is that the outdoor advertisement is impossible to drop or shut down; it is only possible to ignore it in order to avoid it. This might cause the Czech indifference to the advertisement oversaturation, which is often criticised by artists and experts. The aim of the thesis is to analyse and collect the current trends of outdoor extraordinary adaptations with respect to form and content. The theory is followed by the empirical section analysing the data obtained by field research in Prague. Several popular trends were discovered: multidimensional additional structures, special 3D design,...
Pall Ring Manufacturing
Wajda, Jakub ; Kandus, Bohumil (referee) ; Žák, Ladislav (advisor)
The project elaborated design of injection mould with a cold runner system for a creation of component type Pall ring made of polypropylene. Pursuant to of the literary pursuit a problem, the injection technology has been selected as the most suitable method of manufacturing. The proportions of the component along with the placement of the parting line determined the creation process of shaped cavity. The quantity of a manufacturing batch specified two-cavity as the most advantageous variant. The calculation of vent channel’s measurements, the choice of befitting injection machine and a basic simulations had been conducted. The economic part of the thesis has confirmed the suitability of usage cold runner system instead of hot runner system.
The line borders
Kazdová, Kristýna ; Sikora, Piotr (referee) ; Mikyta, Svätopluk (advisor)
The difference in perception of reality is caused by the language that creates the terminology for naming formal entities; the definitions of these concepts are abstract. This creates both a collective inconsistency and an incongruity between content and form. In consequence, the question of the objectivity of attributing an abstract image to specific material should be asked. Elementary elements of the drawing expression as a line/picture are primarily perceived in formal boundaries. The goal of my work is to move beyond these boundaries.
