Use of discrete simulation tools for digital twin creation
Jozefovič, Patrik ; Hromková, Ivana (referee) ; Simeonov, Simeon (advisor)
Digital Twins have undergone significant development since their introduction in 2002. Gradual expansion of capabilities and functions has secured them an indispensable place within today’s manufacturing systems. This work focuses on describing digital twins, as well as levels of enterprise automation. It provides a closer look at the manufacturing execution system as it is directly influenced by digital twins within a manufacturing company. In addition to introducing digital twin technology and related Industry 4.0 technologies, this thesis delves into creating a digital twin for a selected manufacturing system and further explores its capabilities. The practical part of the thesis includes a demonstration of simulation tools for digital twins in the context of optimizing manufacturing processes. Proposed optimizations are then simulated and compared with the initial solution.

Design of a Universal Digital-Twin for the EDUset ONE Robotic Cell
Hrubý, Tomáš ; Hůlka, Tomáš (referee) ; Lacko, Branislav (advisor)
This thesis focuses on the creation of a digital twin for the EDUSet ONE robotic cell, which is part of the Intemac research centre. The theoretical part introduces the concept of Industry 4.0 and describes its sub-elements. The following part of the theory is dedicated to the digital twin, its history, definition and types. It also includes examples of applications in several different sectors of human activity. The next chapter explores the available visualization environments for creating robotic applications. The last theoretical part of the thesis focuses on the robotic cell and its components, which consist mainly of the UR10e collaborative robotic arm and a 5-axis CNC milling machine. The actual solution includes the creation of the twin, which consists of the modification of CAD models and development in Unity. Integral to the practical implementation of the digital twin is the design of the robotic cell scene, the implementation of a wide range of subroutines, a user-friendly interface and an OPC UA client solution for system integration with a Siemens programmable logic controller (PLC).

Modeling of machinery in Matlab/Simulink and Simscape
Moravanský, Lukáš ; Poliščuk, Radek (referee) ; Lang, Stanislav (advisor)
The thesis focuses on the development of a digital twin of the axis of the mould cylinder of a flexographic printing machine for SOMA using MATLAB/Simscape software. Theoretical foundations and concentrated parameter methods were used to develop and validate the physical model, with the main focus on the accuracy of the match with the real system in terms of resonances and aniresonances. A graphical user interface (GUI) was developed to allow easy modification and testing of the model. The work demonstrates the benefits of linking MATLAB tools for developing physics models and provides a basis for future model modifications and extensions.

Use of fluidics systems in robotic applications
Eim, Jakub ; Parák, Roman (referee) ; Matoušek, Radomil (advisor)
The master's thesis deals with the design, production and testing of fluidic elements used for positioning parts in a robotic cell. The aim is to replace vibratory tables and feeders used in pick and place applications with the proposed fluidic solution. The review focuses on currently used products for feeding parts, fluidic oscillating nozzles and air knives. The practical part focuses on the development of fluidics elements using CFD simulations. The design of the 3D model of the robotic station with the implemented fluidic solution was carried out in Solid Edge. The robotic cell was programmed by a digital twin in the Epson RC+ simulation environment. Epson CV2 machine vision was implemented for picking positioned parts with the Epson C8-A1401S manipulator. Finally, the designed fluidics elements were successfully validated on a real robotic cell. The work is concluded by comparing the obtained results with vibration tables.

Modern approaches to maintenance in engineering practice
Vašíček, Martin ; Hájková, Alena (referee) ; Hammer, Miloš (advisor)
The bachelor thesis is focused on maintenance. The first part presents the current maintenance standard entitled "Maintenance-Maintenance Terminology" and the older standard with the same name, which was replaced by the current standard. The work describes the types of maintenance according to each of these standards and compares them with each other. In the second part, modern approaches to maintenance in engineering practice are presented. The third part is focused on one of these modern approaches, namely TPM. The fourth part is focused on the implementation of TMP in two companies.

Dynamic simulations of linear displacement system of CNC milling machine
Gregor, Jiří ; Tůma, Jiří (referee) ; Klíč, Daniel (advisor)
This thesis deals with dynamic simulations of a linear feed system of a CNC milling machine in Adams View. Dynamic simulations enable better and faster decision making when designing new machines than prototyping. The aim of this work is to compare the torque waveforms on ball screws at working feed and at quick feed. The next task is to measure the forces acting on the load body. The values were obtained by simulation in Adams View and measurement on a CNC milling machine MCV Quick 754. The results were exported to Matlab. The resulting torque waveforms were compared, where they are relatively identical during working feed, with large differences during rapid feed.

A vehicle digital twin creation from data acquired during driving tests
Polnický, Vít ; Štětina, Josef (referee) ; Ušiak, Michal (advisor)
The thesis deals with the modelling of the longitudinal dynamics of the vehicle based on the measured data during driving with a electric vehicle. In addition to the creation of the model in GT-SUITE software, the thesis deals with the processing of signals from the vehicle control units. The selected signals are used to generate the efficiency map, the torque speed characteristics of the electric motor and, last but not least, the characteristics of the vehicle battery. To determine the OCV and internal resistance of the battery, a battery model was built in MATLAB Simulink software, where the required quantities were estimated using Parameter Estimator. For simulation in GT-SUITE environment, speed profiles were processed from the measured data. Validation of the model was achieved by comparing the results with measured values.
