Design and Realization of Metamaterial
Kovaľová, Soňa ; Drexler, Petr (referee) ; Nešpor, Dušan (advisor)
The thesis discusses the design of periodic resonant structures, studying of their impact to surrounding electromagnetic field and realisation of magnetoinductive lens with potential application in nuclear magnetic resonance imaging. Frequency tuning of structure by variation of different parameters is described. The finite element method in Ansys HFSS was used to analyse the properties of designed structures.

Concrete slab of family house
Sivčák, Jozef ; Šulák, Pavel (referee) ; Strnad, Jiří (advisor)
The main aim of Bachelor thesis is design and assessment of detached house´s reinforced concrete slab. The ground plan of slab is bent under rake angle 120° and there is a hole for staircase. Internal forces are calculated by finite element method and verified by replacement beam method, but the model for manual design is simplified. Reinforcement is designed for design values of internal forces from finite element method. Outcomes of calculations are building drawings of reinforcement, where the most exposed part, angled part, is solved. Also, tangential internal forces from bended reinforcement in every layer are solved there. Design and calculations were realized by current norms.

The load bearing structure of multi-storey reinforced concrete builidng
Burda, Patrik ; Švaříčková, Ivana (referee) ; Šimůnek, Petr (advisor)
The diploma thesis is focused on design on loadbearing reinforced concrete structure of multi-storey apartment building with shops and offices on the ground floor and underground garage. The thesis consists of the analysis and design of ceiling slabs above underground floor, supporting columns and the beam under the underground floor ceiling slab. Calculation 3D model was created to determine internal forces. All structures are designed according to EC2, ČSN EN 1992-1-1. The thesis includes elaboration of static calculation, shape drawings, drawings of reinforcement of solved structures. The rest of the project part are not analysed.

Structural analysis of part of electrical machine
Fodor, Viktor ; Hájek, Vítězslav (referee) ; Janda, Marcel (advisor)
This thesis discusses the optical diagnostics of electrical motor parts using a 3D scanner. It describes the construction of electrical induction motors, their heat losses, cooling and refrigeration systems that may be used by such motors. It approaches the possibilities of heat recording and briefly explains the 3D scanner’s principal. It also introduces the simulation program ANSYS which uses the finite element method. This thesis shows the post processing of the digitalized object and the simulations and compares the simulation and measurement results. The final part is devoted to the analysis of the obtained results.

Design of mold segment for molding tires manufactured using Selective Laser Melting
Kvaššay, Adrián ; Maňas, Pavel (referee) ; Rapant, Martin (advisor)
This diploma thesis deals with development and design modifications of tire mould segment which will be batch produced by additive technology Selective Laser Melting. Material for its production is maraging steel 1.2709. Lattice structure was used inside the segment construction. The geometry of the lattice cell was chose based on two main factors – eliminating production costs and providing sufficient stiffness. Strength of the segment was calculated by FEM. The functional sample was made and its distortion was analyzed by optical digitalization.

Workshop straightening hydraulic press
Ožvoldík, Daniel ; Tůma, Jiří (referee) ; Omes, Jiří (advisor)
This work deals with the design of a hydraulic workshop straightening press. This press is used primarily for basic operations needed in manufacture, such as straightening the steel plates or shafts. Furthermore, it is be used for bearing assembly or bending metal sheets. The essential parts of this work are the design of the electro-hydraulic circuit, the design of moving the press frame and the analysis of the mechanics of the material.

Stress-strain analysis of the safety frame of the racing car
Kolivošková, Veronika ; Man, Vojtěch (referee) ; Novák, Kamil (advisor)
Topic of this bachelor thesis is the recherché and following deformation-stress analysis of the race car safety cage. This thesis is divided into three parts. The first one is about the introduction of analysis itself and the FIA regulations for homologation static load tests of the race car safety constructions. The second part describes analytical and numerical approach to the deformation-stress solution of a main arch in historical formula 1 car Ferrari 1512. The outputs of these two approaches which were then compared to determine their accuracy and result verification. On this example was executed the contact analysis which was applied in the last part of the thesis. After receiving the results and conclusions from the basic example, the last part deals with the real safety frame model of Subaru Impreza Sti N15. This chapter presents the most important part of the thesis. On the model were executed three static test simulations which have to comply with FIA regulations. The task was solved with FEM modeling.

Computational Models of Transmission Dynamics
Czakó, Alexander ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
This bachelor thesis deals with a summary of knowledge about the computational models of transmission dynamics. Dynamics modelling has different levels of complexity. From the modal, harmonic analysis solved in the FEM, up to creating a virtual prototype in the MBS softwares. In the introduction, there are presented the basics of analytical dynamics and mechanical oscillation which are the basis of individual analysis. Vibration sources in transmission are described as well.
