Robotization of rivet processes
Tomeček, Radim ; Parák, Roman (referee) ; Simeonov, Simeon (advisor)
This bachelor thesis deals with design, creation of 3D model and simulation of robotic riveting cell. The aim is to create movable 3D model of this cell including simulation of riveting process and manipulative operations. The first theoretical part is divided into two main topics – riveting and robotization. Other parts deal with designing, creating and simulating of this model by Siemens software Process Simulate.

Design and implementation of a control program for a robotic cell
Kořenek, Miroslav ; Lacko, Branislav (referee) ; Parák, Roman (advisor)
The aim of an bachelor's thesis is a design and implementation of a control program for a robotic cell. The introduction describes an area of robotic handling workplaces and a division of the area topic. The next chapter deals with Omron compny and its products, especially automation control devices. The next part presents a Fanuc company and its products, especially industrial robots. The following chapter deals with the purpose and design of the robotic workcell and also with a description of system integration. The topic of a last part of the work is the design of control programs for Omron PLC and Fanuc industrial robot. Follows a visualization proposal for an Omron HMI screen. The last part is devoted to testing the designed solution with a simulation of robot with subsequent implementation and testing of the solution on a real robotic workcell.

Design and virtual simulation of single-purpose machine
Klement, Petr ; Husák, Michal (referee) ; Kaczmarczyk, Václav (advisor)
The work deals with the design, simulation and construction of a single-purpose machine. The design is to deal with the robotic operation of the coffee machine. The aim of this work is to get acquainted with the design software Siemens NX and its extension packages and with the program Process Simulate, where the designed single-purpose machine dealing with robotic operation of the coffee machine will be designed, simulated and then made machine. In this work I managed to model all the necessary parts that I use in machines such as coffee maker, mug, mug holder, mug turntable, gripper, mug stand, control box and handles for locking individual parts in the cell. Everything was arranged in a cell and then the phases of storing the cups in a shelf, making coffee in a cup from a coffee machine and moving to a dispensing window were simulated.

Audio signal processing in electronic circuit simulators
Paluřík, Pavel ; Herencsár, Norbert (referee) ; Kubánek, David (advisor)
This bachelor's thesis deals with the simulation of electronic circuits with a focus on the processing of audio signals. At the beginning of the work a detailed procedure and instructions for work in the selected simulation program LTspice are described. The program is free to download, so anyone can try the simulations. The import, processing and export of audio files are also described. The sound of an electric guitar, a spoken word in a male voice, rock and synth recording are then discussed in more details. The last part is devoted to detailed examples of the functions of the tested circuits. The circuits tested are high-pass filter, diode limiter and effect pedal Fuzz Face which is compared with real constructed unit. The verification of the sound from the computer simulation is subjectively evaluated at the end of the work considering similarity of simulated and real recorded audio from Fuzz Face.

Simulations of impact of security requirements on industrial system performance
Loskot, Michal ; Blažek, Petr (referee) ; Mlýnek, Petr (advisor)
Safety and security is always a hot topic in the world of information security, but only a few solve how much cryptographic algorithms affect the performance of systems. Newer longer-key algorithms may provide more security, but it takes longer to encrypt data, that is, they may contain extra bits, which increases transfer time and uses more memory to store additional information. This bachelor thesis is focused on the analysis of the impact of the security requirements of the ANSI/ISA-62443 standard on the performance of industrial systems. Communication is simulated in which cryptographic algorithms AES and SHA were used. These simulations are carried out in the open source simulation tool TTool, which enables embedded systems, hardware and software modeling, and simple simulations directly from UML and SysML diagrams.

Optimization of AC signal voltage amplifier
Vaculík, Lukáš ; Sitta, Michal (referee) ; Šedivá, Soňa (advisor)
The Bachelor thesis deals with the analysis of the voltage amplifier and with simulation of its behavior using program LTspice. The basics for working in this simulation program are also described. The content of thesis is also a measurement of the actual implementation of the amplifier for comparison with the performed simulations. Subsequently, there are outlined possible solutions how to optimize the scheme in order to achieve the best possible results in the monitored parameters, especially the distortion and amplitude of the output signal in the thesis. The scheme was presented by Meatest, s.r.o., where the amplifier is part of a multifunction calibrator. Theoretical part, which serves as an introduction to the issue, describes the components and introduces important concepts, is also included in the thesis.

Selected designing works on the acid water stripping process
Motyka, Ondřej ; Kilkovský, Bohuslav (referee) ; Jegla, Zdeněk (advisor)
The diploma thesis is focused on selected designing works related to the design of a specific process of acid water stripping. The main purpose of the work is to describe the procedure and the obtained results for these performed design work based on the relevant assignment and the process requirements. In the introductory two chapters, the work focuses on process introduction and description of main process equipment. The following chapters are devoted to the description of the designing works, specifically simulation of the process in CHEMCAD, design calculation of the spiral plate heat exchanger for feed preheating, creation of 3D model and drawing documentation using AutoCAD Plant 3D and lastly strength analysis of the selected pipeline. The main outputs of this work are mainly generated result reports from the process and equipment simulation and strength analysis of the solved pipeline route, 3D model of the process and selected technical and drawing documentation. At the end of the diploma thesis, the performed activities and their outputs are summarized and evaluated.

Analysis of thermal behavior focused on additive manufacturing of lattice structures from AlSi10Mg
Nosek, Jakub ; Dočekalová, Kateřina (referee) ; Paloušek, David (advisor)
Using Additive manufacturing it is possible to manufacture complicated components, that cannot be manufactured using conventional methods. The typical example is the lattice structure. Fabrication of these structures is complicated, and it is different from the fabrication of bulk parts. Using numerical simulation which can reflect process parameters it is possible to analyze the thermal behaviour of vertical and inclined struts fabrication. Results show that the diameter of struts influences weld track width. This influence is caused by preheating the powder material by previous scanning paths. The final geometry of inclined struts is made in more scanning layers. In this work influence of the start and endpoint of trajectory is described.
