Loading device for multi-storey bakery oven
Novotný, Jan ; Zborník, Radek (referee) ; Škopán, Miroslav (advisor)
This thesis is aimed at the design of a loading device for a multi-storey bakery oven, which is going to be located in a bread production line. The introduction describes a principle of operation of the bread line and defines the parameters of the device. Furthermore, the hygienic, design and material requirements for the machines which are used in a food industry are briefly stated. Next part summarizes the possibilities of design solutions and the chosen concept. The construction part is aimed at the design of the conveyor and the scissor mechanism. In the calculation part, a static calculation of the lifting mechanism and a strength check of its arms and pins is performed. This thesis also includes the design of a hydraulic circuit for a stroke drive. Finally, the method of a control of the stacker and its safety elements are discussed.

Optimization suggestions of the loading device.
Kršiak, Oliver ; Foral, Štěpán (referee) ; Varmuža, Jan (advisor)
The thesis deals with the contemporary status of a loading device, specially focusing on its weak points and used materials and a design of a new way of connecting parts of the device. It also concerns the means of sealing each individual parts and the choice of materials with low induction of radioactivity. There are shown and described some ways of connection of pipelines, where this is used, in the thesis. In the thesis there are also described various types of sealants. For proper material application in the reactor enviroment, it was necessary to conduct an analysis of components of chosen alloys and their reaction to slow heat electrons and fast electrons. Based on this analysis and other properties, the right alloys were chosen. In the last part of the thesis, there is briefly included the topic of prolonging devices and the way of meassuring the speed of transport.

Nonlinear analysis of reinforced concrete walls
Jurášek, Lubomír ; Vymlátil,, Petr (referee) ; Hradil, Petr (advisor)
Master thesis is based on a doctor thesis dealing with the behavior of reinforced concrete elements stressed shear by the author Ing. Stanislav Martinec, Ph.D. Author master thesis has the task create a spatial finally element model loading testing construction and researched the wall element. Defined finally elements model is mainly to provide proper interaction test device steel frame with the test wall element. Need for sufficiently detailed numerical analysis is necessary to define the non-linear concrete material model, that is researched element, using the extensions multiPlas for calculation software Ansys. The key output parameters, for comparison with the results of load tests, are total bevel and maximum level of applied force on the wall element. The goal is assess the effect of a steel frame, contained in finally element model, to output parameters for by non-linear numerical analysis.
