Testing platform with 3 dof
Spáčil, Tomáš ; Houfek, Lubomír (referee) ; Grepl, Robert (advisor)
This thesis deals with development and construction of parallel manipulator with three degrees of freedom whose assumption of usage is testing tanks for NH3. In this work we are going to investigate the design of the mechanism in Matlab Simulink. Design of the electronic is introduced and also the control program is developed. The result of the work will be a prototype of manipulator.

Utilization of multi-body simulation tools in subject Dynamics
Lokšeninec, Ľuboš ; Houfek, Lubomír (referee) ; Březina, Lukáš (advisor)
The bachelor’s thesis is conducted in purpose of modernization the dynamics theory teaching methods by the multi-body simulation systems. Thesis acquaints student with accessible simulation systems and provides a manual how to compose virtual models of physic frameworks. Student is introduced to the basic options of current multi-body system by means of pre-processed examples focused on rolling, oscillation and inertia moment. Thesis refers to present teaching methods with models composed in Matlab/Simuling system with SimMechanics sublibrary.

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.

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.

Design and implementation of education model "Oscilator 1 dof"
Deďo, Michal ; Houfek, Lubomír (referee) ; Grepl, Robert (advisor)
The purpose of bachelor’s thesis is the design, implementation and testing of the educational model oscillator with one degree of freedom ", which should provide students with the possibility of closer assimilation of events generated by the oscillation, as well as to familiarize the student with the control model through Real Time Toolbox and evaluating the results of measurement. Work should provide students with real-time overview of these problems, which, in the future may bring to light the causes, or even prevention of disorders caused by oscillation.

Simulation model of ABS in passenger car
Svobodová, Jana ; Houfek, Lubomír (referee) ; Grepl, Robert (advisor)
The development of electronics caused revolution the automobile industry. Antilock-Brake-System have become a milestone in the development of electronic security systems. ABS detects susceptibility to locking the wheels, which may occur during braking for critical driving conditions, and then hits. Using of simulation programs is another milestone. Simulation allows repeating of tests and find the best solution of the problem before introduction in practice. Time and development costs are then significantly reduced. In the work is described the most important component of security systems - the braking system and the entire braking process of ABS system. With using a mathematical description of the wheel is in the Matlab-Simulink made quarter model of the vehicle to simulate driving conditions and then created to it a system of ABS. At the end is there an assessment and graphically shown the results of simulations braking.

Rotation Electric Actuator: parameter estimation and control
Palaj, Lukas ; Houfek, Lubomír (referee) ; Grepl, Robert (advisor)
The bachelor’s thesis deals with design of printed circuit board in the first part. The board will be used for connecting rotation electric actuator (REA) to the card MF624. It is written about electronic throttle and it’s particular parts, it’s connection to the card and estimation of parameters necessary for composing a virtual model in Simulink in the second part. After that control for the model is designed.

Design, production and testing of education model "Watt's regulator"
Janoš, Petr ; Houfek, Lubomír (referee) ; Grepl, Robert (advisor)
In the thesis I deal with design, production and testing of laboratory education model "Watt‘s regulator". This work considers different solutions of construction and especially the role of sensors. I assess positives and negatives of each solution. In addition, I describe design and implementation of electronics and wiring for the communication with a PC via control card Humusoft MF624. Using the MATLAB-Simulink and its extensions Real Time Toolbox 4.0 I make the proposal of PID regulator based on Ziegler – Nichols method.
