Soustava těles s pasivním účinkem s brzdou
Genco, Ondřej ; Hájek, Petr (referee) ; Fuis, Vladimír (advisor)
This thesis deals with the solution of the body system using NNTP static theory model. The introductory part defines the basic magnitudes and concepts, describes the constraints and the types of passive effects. In the practical part, the influence of passive effects on different moving states in the particular system of the towed trolley is determined. Furthermore, two variants of mechanical friction brakes are designed and compared. The numerical values of unknown parameters are determined by solving the system of linear equations in Matlab.

Analýza soustav 6-ti těles s vazbami s pasivním účinkem
Krček, Aleš ; Marcián, Petr (referee) ; Fuis, Vladimír (advisor)
This bachelor thesis deals with analysis of the systém of six solids with links with passive effect. The first part deals with theory which includes basic terms of statics, description and characteristics of the neutral and passive links. The second part comprises of two examples that the influence of passive effects on the motional state are demonstrated on. Aim of each example is the calcuation of contact forces in links and the evaluation of function of links and the motional state. The solution is carried out with the computing software MATLAB.

Rear cover hinge design of car
Bílek, Vojtěch ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
The thesis deals with the issue of suspension of the 5th passenger car door. The introductory part deals with the possibilities of mounting the 5th passenger car door. In the next part, a HDS hinge was selected, which is further solved using a numerical and experimental method. Aluminium alloy was used on this HDS hinge to reduce weight. In the first step, a technical experiment was performed on the existing state (steel) and a strain-strain analysis was performed. Based on the stress-strain analysis of the material change variant without structural change, unsatisfactory results were obtained. After that, design changes were proposed such as increasing the thickness of the tube wall in the Creo program, and this variant was also subjected to a stress-strain analysis using the numerical modelling. Comparison of the results was based on the values of elastic deformation and equivalent stress. Finally, the thesis dealt with the manufacturability of the proposed component within which, a technical experiment was carried out.

Precast concrete structure of production hall
Hradský, Richard ; Kostiha, Vojtěch (referee) ; Girgle, František (advisor)
The main part is design and calculation of the transversal frame of industrial building consisting of those parts (girder, column, foundation pad). Computational software SCIA ENGINEER is used for design, calculation and drawing of those forces, moments and stress of elements. The verify of the results and their accuracy is applied handdone static calculation of forces, moments and stress. The drawings of those elemenst will be producted by Computational and drawing software ArchiCAD.

The production of cover blowers
Soldán, Josef ; Řiháček, Jan (referee) ; Císařová, Michaela (advisor)
This thesis is focused on the production of cower blowers from steel sheet 1.4541. As the best method for producing of this part was selected bending in the bending press. This choice was based on literature review, geometry of bended part and amount of production order. For each bend was calculated bending force, position of the neutral layer and size of the springback. Bending tools and bending press were chosen depending on the biggest bending force from the bends. Developed length of the part was calculated by the position of the neutral layer. All of the above calculations were numericaly verified by the ANSYS simulation software for the last bend.

Aggressiveness, aggression
Matesová, Radka ; Koťa, Jaroslav (advisor) ; Krykorková, Hana (referee)
Annotation: This thesis deal with aggresion and aggressiveness in humans lifetime, its sorts, starters.In more detail it is focusing for some forms of aggressive behavior as are chicane, ill-usage, racism, anti- semitism. It determinatives them as notions, describe thein after- effects and thein resolutions. At the conclusion this thesis offers set of games, methods and lessons for aggressiveness absorbing of pupils in the school. Some of them are equiping with photos, and the educt of simple questionnaire on the theme aggressive behavior at primary school in region Mladá Boleslav.

Actions on bridges caused by the water flow and floating items
Řezník, Jindřich ; Duchan, David (referee) ; Špano, Miroslav (advisor)
The subject of this thesis is the enumeration and analysis methods applicable to the calculation of loads on bridges from water and water-borne objects. It involves a hydrodynamics loads, loads from captured debris and from impacts of the individual water-borne objects and their clusters. It includes an assessment of the current situation, the teoretical analysis and model calculations on the concrete bridge with the evaluation of usable methods.

Design of Device for Tyre Rolling Resistance Measurement
Piskoř, Martin ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
The aim of this thesis is a construction concept of tyre rolling resistance measuring device. The first part deals with the rolling resistance. It describes its causes, its influential factors and it also includes rolling resistance identification methods. The second part deals with construction design of the rolling resistance measuring device itself. It contains stress analysis, and fatigue analyses as well. It includes selection of transducers used for tyre rolling resistance measuring and also measurement error analyses. The last part focuses on estimated financial requirements connected with producing and assembling the designed measuring device.

Measurement of elektrical and nonelectrical quantities of motor drive for switchgear
Pěček, Dominik ; Dostál, Lukáš (referee) ; Valenta, Jiří (advisor)
Bachelor’s thesis deals with measurement of electrical and non-electrical quantities on motor drive MP-BD-X230. As an introduction the classification of drives for switchgear is analysed and circuit breaker BD250 is described. Thesis continues by explaining application, basic nature and design solution of motor drive MP-BD-X230. Another step is description of workplace and devices which will be used for measurement. Measurement procedure of electrical and non-electrical quantities is also carried out accompanied by evaluation of measurement. Final part of the work deals with calculation of uncertainty of measurements with a reference to each individual measurement calculation and also deals with determination of measurement errors.
