Napěťová, deformační a bezpečnostní analýza statoru generátoru zatíženého nehomogenní teplotou / Stress, deformation and safety analysis of the generator stator loaded by nonhomogeneous temperature

Majdič, Petr January 2015 (has links)
This thesis deals with stress, strain and reliability analysis of synchronous generator stator including an inhomogeneous temperature field. Using the finite element method, stress and strain are calculated, and from these values safety against yield strength is determined, which is followed by the life calculation of the most stressed weld joint and the determination of its possible damage during the period required by the customer.

Vliv rozptýlené výztuže na průběh zrání polymercementových hmot / Dispersed reinforcement influence on the maturation of polymercement materials

Zaťko, Petr January 2017 (has links)
The diploma thesis is focused on polymercement materials with dispersed reinforcement. The aim of this work is development of suitable polymercement mixture and monitoring of the impact of dispersed reinforcement on the course of maturation of these materials and physico-mechanical properties. The effect of high temperatures on the properties of the mortar is also examined. Emphasis is placed on the use of alternative resources and byproducts. Mixed binder of cement and slag and admixture of microsilica was used. Recycled cellulose was used as dispersed reinforcement and was compared with commercial polypropylene fibers.

Nelineární analýza bezstykové koleje v obloucích malého poloměru / Nonlinear analysis of continuous welded rail in curves of small radius

Murínová, Klára Unknown Date (has links)
The diploma thesis examines the influence of curve radius on continuous welded rail stability in a small radius curve. Attention is paid to curves with a radius less than 300 m. The first part of the thesis summarises the theory of continuous welded track and influence of track parameters on track stability. The second part of the thesis deals with constructing of the numerical model of a curved track with the observed behaviour of track under thermal loading with positive and negative temperature values. The variable values in the model are rail shapes and different radius. In the end, the shape of the track lateral deflection as a function of temperature are evaluated.

Experimentální metody v energetickém hodnocení / Experimental Methods in energy assessment

Palík, Lukáš January 2015 (has links)
The final thesis is focused od the experimental metods in energy rating of building. In the first part is described history of energy rating from the eigtheens to the present and described is the current trend of energy rating in terms of energy performance certificates. In the second part is elaborated energy assessment for apartment building from bricks with six residential units. For the building is drawn a total of 6 measures, of which there are 3 structural and 3 for building equipment. The measures are assembled to variants and the resulting variant is recommended, including recommendation. In the last experimental part is described the influence of shading elements on the thermal load of the room and modeled the effect of insulating double glazing and triple the overall energy performance reference room.
