Virtual prototype of mechatronic system in ADAMS
Sojka, Tomáš ; Andrš, Ondřej (referee) ; Vetiška, Jan (advisor)
This thesis deals with the process of creation of virtual prototypes of mechatronics systems. Virtual prototypes are formed by combining different models, each of which simulates the specific characteristics of the system. Itself reduce the cost and time of development that there is no need physical prototypes. The first part consists of a short search on the modeling of virtual prototypes using a mechatronic approach. In the second part is created a virtual prototype of the mechatronic system - two-axis manipulator using programs MSC.ADAMS and Matlab / Simulink. Controlling of this model works in co-simulation mode.

Software for processing data from the accelerometer
Zahradník, David ; Vetiška, Jan (referee) ; Kovář, Jiří (advisor)
This thesis deals with the creation of software for statistical processing of data from the accelerometer. In the first part are specify the objectives. The next part of the thesis is followed by design and creation software for statistical processing of data in real-time as well as post-processing mod. Final program is tested by using stored data from the accelerometer. At the end the functionality of the created software is evaluated. This program is created by using the programming language C #.

Active Balancing of Machine Tool Spindle Units
Pěnčík, Martin ; Vetiška, Jan (referee) ; Březina, Tomáš (advisor)
The aim of this bachelor’s thesis is to do background research of active balancing, to design a simplified model of spindle with an active balancing system and to realize searching simulations. The research describes basic terms and methods which are necessary to understand the issue of balancing. Then, the principle of both classic and active balancing and the description of an active balancing actuator are stated in the paper. Moreover, the thesis presents the creating process of the model which was performed in the program Matlab/Simuling. The thesis presents detailed descriptions of the realized simulations, the results of the simulations and a subsequent result analysis.

Machine Tool Spindle Units: Active Tool Deflection Compensation
Zarboch, Jaromír ; Vetiška, Jan (referee) ; Březina, Tomáš (advisor)
Cutting forces during milling process cause tool deflection. There are several methods for compensation of this deflection. This paper is focused on the active method of tool deflection compensation which angles adaptronic spindle by piezoactuators to compensate the tool deflection. For this method the simulation model was built in programe Matlab / Simulink. The effectiveness of this model was validated by search simulations.

Shock Absorber for Generating of Electrical Energy
Maťaš, Marek ; Vetiška, Jan (referee) ; Hadaš, Zdeněk (advisor)
This these is considering with possibilities of generation of electric energy, with use of linear generator in automotive industry, that linear generator is replacing shock absorber. Subsequently the base model of shock absorber is used and excited with sinus signal. From this simulations are got the results of damping and power. Then it will be made a simulation of shock absorber, with known parameters of damping, mass of vehicle and real model of road. Then it is made control with PID regulator.

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.
