Mechatronic Proposal of Electromagnetic Vibration Power Generator
Jurosz, Pavel ; Houška, Pavel (referee) ; Hadaš, Zdeněk (advisor)
This thesis deals with modifications to the construction of vibration-to-electricity energy converter, which is one of possible solutions to problem of sustainable and stable energy source for wireless sensor supply. Upon the exploration of the present state of this problem, new construction of generator is proposed. The aim of this proposal is to enhance the existing generator properties with respect to retention of its dimensions and its weight. Results obtained by simulations of model with proposed parameters are presented and analysed.

Optimalization of vibration microgenerator
Kurfűrst, Jiří ; Hadaš, Zdeněk (referee) ; Ondrůšek, Čestmír (advisor)
The article describes how to produce energy necessary for sensor supply. These generators are used as a local source operating on vibratory principle. Mechanical vibrations that occur in moving machines, in nature etc. are used in order to gain required energy. So are kinesis principles and analysis employed in some of the avaible generators. It also contains patent and literary background research. Work is oriented to solving mechatronic perimeter, in the concrete micro - generator. Mechatronic perimeter piles from seat power control parts and mechanical parts, where common solving equation system leads to correct solving. Mentioned analyses be of consequence for usage optimization methods artificial intelligence. Optimization method are used on optimum solving proposal micro - generator. To inquest dynamism system was used program Simulink (part of MATLAB), generator is buckthorn for f = 17 [Hz] acceleration yam = 0,5g [ms-2]. As a algorithm is used SOMA – All to one.

Vibration Harvester for Aircraft Applications
Rubeš, Ondřej ; Vetiška, Vojtěch (referee) ; Hadaš, Zdeněk (advisor)
This thesis is focused on modification of a design proposal of a vibration energy harvester for autonomous aircraft applications. Vibration energy harvester is mechanism, which converts vibration energy to electric energy. Its main parts are oscillating mass, magnets and coil for electromagnetics induction. The thesis is consisted of simulations of magnetics circuits, creating 3D model of harvester and simulations of oscillations with parameters from 3D model, magnetics simulations and with input sample of exciting vibrations.

Modelling of mechatronic system with flexible parts
Kšica, Filip ; Vetiška, Jan (referee) ; Hadaš, Zdeněk (advisor)
This thesis deals with the simulation modelling of mechatronic system with flexible parts using ADAMS and Matlab/Simulink. The beginning of thesis is dedicated to the summary of available methods of modelling mechatronic systems with flexible parts. Next chapters describe different approaches of modelling flexible parts using analytical and numerical methods. In the following step, model of particular mechatronic system is created. System itself consists of a flexible beam part, electromagnetic vibration exciter and vibration power generator. Each part of the system is created separately in variety of programmes, including FEMM, ADAMS and Matlab/Simulink. At the end of this thesis, co-simulation of ADAMS and Matlab/Simulink is used to describe behavior of the complete system, especially energy conversion efficiency of vibration power generator and its impact on the system.

Energy Harvesting for Automotive Applications
Novotný, Jan ; Kovář, Jiří (referee) ; Hadaš, Zdeněk (advisor)
This thesis goal is to get information about Energy Harvesting and subsequent confrontation of it. The Energy Harvesting technology deals with process of absorption so-called free energy and conversion it into electric energy. The reason for doing that is mostly feeding wireless sensors. When the search in this area is accomplished on bases of existing constructional principles the concrete device (generator) is designed. This system might be unlimited power source for selected automotive application.

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.

Walking as alternative source of electrical energy
Smilek, Jan ; Hejč, Tomáš (referee) ; Hadaš, Zdeněk (advisor)
This thesis deals with problematics of using the Energy Harvesting principles for generating power from the human walking. Own acceleration measurement during walking was made on various locations of human body to provide data for self-developed MATLAB/Simulink energy balance script. The script clearly sets the possibilities and limits of vibration generator used in this application. Conclusions of the energy balance were used to specify requirements for development of vibration generator and few possible conceptions, working on frequencies close to 2 Hz and acceleration amplitudes 0,3 g, were presented, or simulated.

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.
