Experimentální a numerická analýza zesílení železobetonového vetknutého prvku / Experimental and numerical analysis of strengthened reinforced concrete member with rigid boundary conditionsPtáčková, Kristina January 2012 (has links)
A proposal how to conduct a compression test of reinforced concrete objects with one beam inserted from both sides exposed to a four-point bending. A theoretical proposal of the most appropriate form of reinforcement of the reinforced concrete object including a suggestion how to increase its tensile strength based on the chosen crushing load and the positioning of the beam (static calculation). Presentation of the project, static compression test measurement and all the other necessary measurements (elastic modulus, strenth of the material etc.). Development of a mathematical model with the help of Atena software. Evaluation and comparison of the results in analytical and experimental part of the project. Recommendations for implementation of similar experimental tests.

Optimalizace uložení ložisek převodovky domíchávače / Optimization of mixer truck gearbox bearing arrangementsGórnisiewicz, Tomáš January 2015 (has links)
This diploma thesis deals with a design and optimization of mixer truck gearbox bearing arrangements. The gearbox is an important part of mixer truck. Major emphasis is put on design of main bearing which is a key component of the gearbox because of high load applied on it. Two basic criterions were considered in main bearing design – dynamic radial load capacity and contact stress in contact of roller and raceways. Developed two-stage optimizing algorithm is based on standard bearing and allows to design new bearing which is specialized for carrying output shaft of mixer truck gearbox.

Výpočet plastické únosnosti desek / Analysis of plastic bearability of platesRozsypalová, Veronika January 2013 (has links)
The subject of this thesis is analysis of the plastic bearability of plates. The first part is dedicated to a description of pertinent theories. It is primarily a theory of material nonlinearity and plasticity, including a description of plasticity models, which are commonly used in engineering analysis. Next is the hinted theory of geometric nonlinearity and discusses the key principles of limit plastic bearability of plates. This thesis includes ultimate strength calculations of plates of selected shapes, their solution by both, a manual calculation and using computational software. The obtained values are subsequently evaluated. The appendices contain the procedures for modelling in the computational programs RFEM and ANSYS.

Návrh dvoumotorového letounu pro sběrnou dopravu dle předpisu CS-23 / The design of a twin-engined airplane in the commuter category according to CS-23 regulationDula, Jan January 2011 (has links)
This work's objective is to create a type design of a new commuter class airplane according to CS-23 certification specifications. The design will take under account the EV-55 design to reduce the number of new parts and subassemblies. Part of this thesis are mass balance of the new design, basic airplane dimensions and fuselage dimensions estimates. The critical crossection of the fuselage is analyzed (stress analysis) and the system drawings is worked out.

Pevnostní analýza nosníku s tenkou stojinou - vliv otvorů a tahového pole / The Stress Analysis of the Beam with Thin Web - Influence of the Holes and Tensile Effect of Web BucklingHorák, Marek January 2014 (has links)
In design of an aircraft structure, the great emphasis is placed on achieving high weight efficiency. This thesis is focused on the stress analysis of the spars with thin web with or without web openings, which is one of the most important parts of the airplane structures. In comparison with traditional spars or beams, which are widely used in civil engineering applications, the design of the beam with thin web is more complicated. Thesis contains useful information for analytical calculation of this type of spars and its verification using finite element method and experimental measurement.

Aplikace metakaolinu v žárovzdorných materiálech / Application of metakaolin in refractory materialsTvrdík, Lukáš January 2016 (has links)
Refractory materials are irreplaceable in all industrial fields where it is necessary to use high temperatures. This paper deals with the use of metakaolin in refractory materials that allows the operation of such facilities. In recent decades has the development made significant progress in quality parametres, which extended life period of refractory materials in their use and significantly decreased the specific consumption of refractory materials in various technologies. This phenomenon is also called "harakiri effect". At the same time a constant pressure to the lowest prices of products is on the refractory market. Metakaolin seems to be appropriate raw material, which may help to achieve interesting qualitative effects. It may affect many properties of the influence on the behavior of materials during processing, through physico-mechanical parameters and dipping to the economic efficiency of production.
