Design of sand blasting machine modification
Klár, Pavel ; Fuis, Vladimír (referee) ; Krejsa, Jiří (advisor)
This thesis is focused on design and implementation of structural adjustment of sandblasting machine with regard to the requirements of resolution. The first part consist of short study describes a blasting technology and various types of blasting machines. Second part – practical part consists of problem analysis and setting goals to be achieved. The main goal of the design is to not influence the machine and to limit presence of the operators by modification in the actual process of sanding. There is also detailed design of solution’s proposal which fulfills the specified goals and is supported by calculations. Descibed design was realized and preliminary results suggest that pre-defined goals are met.

Loading of the crane-runway girder
Vrbka, Dušan ; Fuis, Vladimír (referee) ; Suchánek, Miroslav (advisor)
The main purpose of this bachelor project is to solve Loading of the crane-runway girder. First of all, we located the possible dangerous places where we solved the running of Shear and moment diagrams which depends on distance of loading forces p from the beginning of the crane-runway. For the mathematic solutions, we used specialized software MAPLE. The main advantage of this software is the ability of the analytic analysis. We introduced the method of the solving the crane-runway girder on three supports. The final part shows the main results and highlights the most strained parts with suggestions for decrease loading level of strained parts.

Planar frames and curved bars. Study of the significance of the influence of normal and shear forces on deformation characteristics of the centerline
Donát, Martin ; Fuis, Vladimír (referee) ; Suchánek, Miroslav (advisor)
The Aim of this thesis is to write up the relevancy of particular resultant inner effects (further denoted as RIE) on the central line bars and plane frames deformation. The relevancy of particular RIE on the choice deformation characteristic bars in dependence on the ration of central line length and characteristic cross-section proportions, support type and bar load is analyzed in the sample examples. We solve a problem whether a bent bar should be comprehended as a shall bent or as a forte bent bar and we also analyze how does the stiffness shift influence the fractional bar deformation. When solving the sample examples we suppose that the bar expectations are fulfilled. When determining the central line deformation we use the Castiglianano’s theorem because it enables to include supplies of particular RIE.

Engineering Mechanics 2011
Fuis, Vladimír
The objective of the 17th conference is to provide a forum for researchers to discuss the state-of-the-art in Mechanics of Solids, Fluids and Thermomechanics, this particularly in connection with problems under investigation in the Czech Republic. Problems of Engineering Mechanics related to the contemplated topics can be discussed, and their solutions presented, during the sessions of the Conference, held at the Hotel of the ŽĎAS, a.s., situated in the beautiful countryside of the Žďár Highlands.

Napjatostní analýza keramické hlavice totální kyčelní endorpotézy s mikro a makro tvaovými odchylkami
Fuis, Vladimír ; Hlavoň, Pavel
The paper deals with the problems of ceramic head of hip joint endoprosthesis destructions in vivo, and with assessing the impact of shape deflections of conical surfaces on the tensile stress in the head. There are assumed two material characteristics of the stem – the first is linear elastic and the second is bilinear plastic modelled austenitic steel used in the bio-implants. Concerned are shape deviations from the ideal conical surfaces of the stem and the head of the endoprosthesis. The shape deviations may be modelled at the macro-level - this concerns model shape inaccuracies such as deviation from the nominal degree of taper, at the micro-level - when the stochastic distribution of unevenness on the contact areas is respected. The problem of stress in ceramic heads was solved using the algorithm of the finite element method – system ANSYS under ISO 7206-5 loading.

Napěťově deformační analýza fotovoltaické elektrárny
Fuis, Vladimír ; Venclík, J. ; Ždímal, P.
The paper presents the results of the analysis of the optimization of the photovoltaic power plant construction with regard to its weight (maximum weight of the plant construction – without photovoltaic panels – must not exceed 50 t) while ensuring that the construction is safe against the plasticity of the construction and the loss of buckling stability of steel rods.
