Complex design of industrial manipulator analysis
Peml, Luboš ; Houfek, Martin (referee) ; Březina, Lukáš (advisor)
The work deals with analysis of industial manipulator complex design procedure and demostrates major issues of that procedure on plannar manipulator example using Simulink and MSC Adams.
Dynamic analysis of oscillations with multiple degrees of freedom
Schulmeister, Jiří ; Houfek, Lubomír (referee) ; Březina, Lukáš (advisor)
This thesis is dealing with analysis of oscillating with multiple degrees of freedom and with example of dynamic behavior of system with two degrees of freedom with different input signals for purposes of dynamic lessons. Conventional method of making equations of motion by Lagrange’s method and their consecutive analysis is inscribed in the work. As example of system with two degrees of freedom is chosen quarter car model. Responses to different input signals are shown for the model. It is made in MATLAB/SIMULINK.
Test of Vibration Power Generator with Transversal Coil
Drbohlav, Jan ; Březina, Lukáš (referee) ; Hadaš, Zdeněk (advisor)
This work deals with the installation and testing the parameters of the electromagnetic vibration generator, designing of construction modifications and creating numerical model describing responses of generator in MATLAB Simulink.
Test of Vibration Power Generator with Longitudinal Coil
Stejskal, Jan ; Březina, Lukáš (referee) ; Hadaš, Zdeněk (advisor)
This thesis deals with activation and testing of Vibration Power Generator with Longitudinal Coil which was designed at Brno University of Technology. One of goals of the thesis is to compile simulating model of this device and to compare its results with data gained from measuring device used while testing on the vibration stand. This Vibration Power Generator could be theoretically used in aerospace industry as well as in other branches of industry. It´s important to minimalize its dimensions and weight as much as possible. On the other hand, there are some parameters which should stay unchanged with respect to troublefree work of the device. According to those facts, some changes of construction were proposed within this thesis.
Overview of methods for person identification using image processing
Palacka, Martin ; Březina, Lukáš (referee) ; Krejsa, Jiří (advisor)
This thesis deals with an overview of methods for person identification using image processing. The beginning of thesis is dedicated to the theoretical study of the skin segmentation method, its algorithm and different color spaces, which are used for identification by this method. The next algorithm is a method called boosted cascade of simple features, while focusing on description of this method, an OpenCV library, computing algorithm, image interpretation by integral image and speed of computation which is reached. The next chapter describes the PCA method, the principles of working, a description of the mathematical model, a study of gender recognition, the results and troubleshooting. The last described methods are fusion of facial strips and pixel patern based texture feature. At the end of this thesis there is the tested application of person identification and gender recognition and the results of the success of methods.
Simulation modeling of RPR parallel kinematic machine
Hvížďala, Jan ; Houfek, Lubomír (referee) ; Březina, Lukáš (advisor)
The work is dealing with simulation modeling of a parallel kinematic machine RPR. There is described an approach of creating the simulation model. There was constructed a model of kinematics and dynamics of the mechanism in MSC Adams which was consequently compared with the model created in MATLAB/SimMechanics.
Simulation modeling of a vibration absorber
Kukačka, Radek ; Vetiška, Jan (referee) ; Březina, Lukáš (advisor)
The bachelor thesis gives an overview of different design solutions to car shock absorbers. The rest of the thesis describes a simplified model of passive shock absorber and its optimization. The survey contains shock absorbers used in the present. There are various passive telescopic dampers and modern semi active and active electronically controlled damping systems. The second part includes several simplified models of passive dampers. There is described an optimization of the damper parameters with respect to the displacement of the primary mass for each of the models.
Experimental analysis of a fixed beam dynamic behavior
Poduška, Jan ; Houfek, Lubomír (referee) ; Březina, Lukáš (advisor)
This thesis is dealing with analysis of dynamic behavior of a fixed beam. An analysis of the applied mathematical model is proposed in the work. The mathematical model is then realized in MATLAB programming environment. Modal frequencies and mode shapes are con- sequently computed and results are compared to those obtained from the experimental modal analysis.
Mechanical construction of hydraulics arm
Vodrážka, Jakub ; Březina, Lukáš (referee) ; Věchet, Stanislav (advisor)
This bachelor’s thesis deals with design of a hydraulics arm. The main purpose of this hydraulics arm is the possibility to use it in education project which is a part of hydraulics systems lessons. This arm consists from few parts which are connected together by rotary joints. This arm is actuated by linear hydromotors, furthermore there is a magnetic position sensor. Autodesk Inventor 2008 was used during the arm design process. There are three main parts in this work. First part deals with fluids systems, the second part shows the position sensor properties and the last part presents some cases of arm design with deformation verify. A lot of supplement is presented at the end of this work as pictures of the model of the arm or pictures of some parts of the model.
Design of Electromagnetic Part of Vibration Power Generator for Low Frequency
Konrád, Libor ; Březina, Lukáš (referee) ; Hadaš, Zdeněk (advisor)
The project deals with contemporary position of vibratory generators based on electromagnetic principle and optimal constructional solving of electromagnetic part of generator. Practical part is searching for suitable solving of construction of electromagnetic part of vibratory generator in the light of required power. Solving is brought to effect by the simulator simulation. Vibratory generator works in frequency range 17Hz. Final suggestion has to answer requirements of observance of frequency ranges, minimal power and simple production. Project includes simulation model as well as proposal of final form of modified generator.
