Casting production of an optimized inlet shape of pneumobile engine pneumatic cylinder
Bouchner, Jan ; Záděra, Antonín (referee) ; Krutiš, Vladimír (advisor)
Presented bachelor's thesis deals with production of a pneumatic component using hybrid investment casting technology. This method combines investment casting with additive technologies. The manufactured component, called cap-end, supplies compressed air to the pneumatic drive of a racing car. Complex design of this component was created using computer fluid dynamics optimization. This design was delivered by the Pneumobile racing team Brno. Presented thesis further contains a technological consideration taking into account solidification direction, on the basis of which the delivered geometry was modified. Manufacturability of the component is verified by a numerical simulation in the ProCAST environment. This thesis also describes printing process of a combustible model using fused deposition modelling technology. The combustible model is used in the production of a ceramic shell. Using said ceramic shell AlSi10Mg alloy casting was made. The component had to meet the requirements for leak tightness after machining and subsequent assembly. The leak tightness is assessed here as a pressure drop in a closed circuit measured over time. Furthermore, the effect of the cap-end on properties of the racing car in relation to the original geometry was investigated. The comparison is made on the basis of the race car's unloaded wheel speed measurements. The outcome of the thesis is a functional cap-end component that validates the results of a scientific article published by members of the Pneumobile racing team Brno.

TITLE: The technological support of the Storytelling teaching method AUTHOR: Jan Bouchner DEPARTMENT: Department of information technology and technical education SUPERVISOR: Ing. Bořivoj Brdička, Ph.D. ABSTRACT: The subject of this dissertation is the use of digital technologies to support storytelling in the classroom. This thesis aims to introduce storytelling as an innovative method based on the principles of modern pedagogy, especially social constructivism, and determine the role of this methodology in the current curriculum. Another objective is to provide a comprehensive overview of methods and activities of digital storytelling including the examples of hardware and software instruments. Their value for practical use in digital storytelling was verified. The analysis of scientific literature was used in the theoretical part of this study. The work also includes the description of two cases of implementation and a description of their realization. In the conclusion the recommendations for the use of digital storytelling in practice are formulated. KEYWORDS: storytelling, methodology, constructivism, designing, educational technology
