Model of the bridge for presentation of the member system
Chlup, Pavel ; Krejčí, Petr (referee) ; Appel, Martin (advisor)
In this bachelor thesis, the individual parts of the model bridge structure are explained with a brief commentary on their creation. Subsequently, the computational modelling of the problem using statics and its practical solution using strain gauges and MATLAB software is elaborated upon. The thesis is divided into a total of four chapters, where the first one is devoted to research on the application of statics and strain gauges. Subsequently, the function of each part of the fabricated model is formulated and a static model of the truss system which is equivalent to the fabricated model but is statically indeterminate without further considerations is presented. Then, the principle on which strain gauges are applied to solve the insolvability of the system is explained and as a result, the force action in the truss system as a function of the load is plotted using an application developed in MATLAB software. The result is a comparison of the measured and calculated values in the truss system.

Stress-deformation analysis of the indoor basketball construction
Kubíček, Daniel ; Kovář, Jaroslav (referee) ; Fuis, Vladimír (advisor)
The topic of this thesis is stress-strain analysis of a basketball structure in a gymnasium. This structure is divided into two parts. One part is modeled as a spatial bar system. The other part is modeled as a plane bar system. The first part of the paper deals with the research on the use of bar systems in sports. This is followed by the development of analytical computational models of the spatial and plane bar systems. These models are then used to calculate three different loading conditions. Subsequently, the models are developed for numerical solution. In the last part of this work, the analytical solution is verified by the numerical solution.

Steam boiler burning fytomass waste
Plot, Rostislav ; Skála, Zdeněk (advisor)
This thesis deals with the calculation of the boiler on stillage. Nowadays, when there's fossil fuels are just biomass seems adequate compensation. The great advantage of biomass boilers is a small amount of emissions, especially the greenhouse gas CO2. Of a given fuel composition is made thermal calculation and dimensioning of heat transfer surfaces of steam boilers. The resulting calculation must follow the parameters of steam at the outlet from the boiler.

Tyre Temper. Meauserement on Moving Vehicle with Use of Infrared Pyromether OS100
Morávek, David ; Rasch, František (referee) ; Blaťák, Ondřej (advisor)
Bc. David Morávek Tyre temperature measurement on moving vehicle with of infrared pyrometer OS100 MT, IAE, 2008, page 70, picture 41 Problemacy of recording the temperature and tyre pressure on driven car is processed in this diploma work. Suitable measuring chain was set up. Censor holders for this type of measurement were designed and produced. Driving exams and tests are depicted in this work, too. We came to the conclusion that tyre temperature depends on lengthways and transverse acceleration of the car and also on it’s load.

Design and realization of the pull strength measuring device for SMD
Valíček, Jan ; Klíma, Martin (referee) ; Otáhal, Alexandr (advisor)
This thesis deals with the design and implementation of a device for measuring pull strength by surface mounted devices (SMD). It analyzes the theory of pull strength testing of solder joints with emphasis on standard IEC 62137-1-3 and describes the selection of components utilized to create mechanical construction and electrical parts. These electronic parts made or innovated in this work were control system based on microcontroler Atmega164P, power circuit for stepper motor and communication of measure equipment TEST 321 with PC. The whole design is complemented by simulation of mechanical stress to the critical components using ANSYS. The conclusion summarizes the most important parameters of this equipment.

Stress-strain analysis of a crane arm
Mora, Lukáš ; Halabuk, Dávid (referee) ; Fuis, Vladimír (advisor)
The content of this bachelor’s work is a summarization of types of tower cranes and subsequent stress-strain analysis of the crane arm of the crane type 150EC-B8 Litronic located on the Šumavská street in Brno. Analytical stress-strain analysis is calculated with equations of equilibrium using joint method in various types of loading of the construction with MAPLE software. Numerical calculation is executed on 3D model of the construction in software ANSYS. The aim of this bachelor work is the verification of the correctness and comparison results of analytic calculation with numeric calculation and evaluation of the results from a limit states and deformation standpoint.
