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.

Asset Administration Shell for PLC
Maslowski, Jakub ; Arm, Jakub (referee) ; Benešl, Tomáš (advisor)
This bachelor work gradually summarizes the findings regarding I4.0, as well as its basic parts (AAS, RAMI and DT). Subsequently, it focuses on the description of AAS with regard to the necessary compromises from its original idea with the aim of its successful implementation in PLC, which represents some limitations. The work includes solutions of suitable communication protocols for AAS in PLC. The practical part focuses on the implementation of AAS in PLC from Siemens S7-1200 series using OPC UA methods. SiOME and UaExpert programs are used in the creation. The thesis contains detailed instructions for replication of AAS implementation together with suggestions for possible improvements and its benefits in practise.

Use of Modelling and Simulation in the Analysis of Operational Risks of Production Lines
Wolker, Jakub ; MSc, Martin Manga, (referee) ; Lacko, Branislav (advisor)
The diploma thesis deals with the use of modeling and simulation in the analysis of operational risks. Proposals for the methodology for creating a digital twin model of new and existing production lines, subsequent verification of the methodology on a specific model and also the use of the model to determine operational risks will be presented. Siemens Tecnomatix Plant Simulation software is used to create the digital twin model and to verify risk scenarios and related experiments. The main goal of this work is to propose a suitable procedure and means that address the issue of planned benefits and risks for production line projects. This is achieved by meeting the sub-objectives that correspond to the individual proposals. The solution is based on theoretical knowledge and analysis of the assembly line, the state of value stream mapping and the data used.

Modelling of the Gear Pump Manufacturing
Horák, Michal ; Rožňák, Ing Martin (referee) ; Videcká, Zdeňka (advisor)
The diploma thesis deals with the analysis and optimization of production lines of the gear pump components. Specifically, it is pre-production, ie a production line for machining gears and production line for machining of bodies. These two components are then assembled on the assembly line. The creation of a simulation model in the Tecnomatix Plant Simulation program, which corresponds to the real state of production lines, is used for optimization. The simulation model is then used to perform the proposed experiments in order to optimize production lines and select the ideal solution with respect to the selected objectives.

Virtual twin for testbed Industry 4.0
Husák, Michal ; Pásek, Jan (referee) ; Kaczmarczyk, Václav (advisor)
The goal of my master‘s thesis is to create a digital twin of a testbed Barman. The Barman is a school model of autonomous mixed drinks production line that demonstrates the principles of Industry 4.0. In the theoretical part of the thesis, the choice of a suitable tool for virtualization is discussed. The Tecnomatix Process Simulate and the Mechatronic Concept Designer module integrated in the NX platform is compared. The practical part of the work is divided into two phases. The first phase was about looking for a way to integrate the robotic SCARA manipulator. The second phase was focused on the virtualization of the cell Shaker in the latter of the tools mentioned before. This work is designed as a guide for creating and verifying the concept of a digital twin.

Use of Head-mounted displays in risk management for machine tools
Jelínek, Martin ; Kotek, Luboš (referee) ; Tůma, Zdeněk (advisor)
This diploma thesis deals with the design and technical possibilities of VR headsets and their application in mechanical engineering, specifically in the field of risk management in machine tools, using experience from other areas and history. The practical part of the thesis comprises a risk analysis carried out on a single selected machine (vertical machining center) by means of checklists and virtual technologies. The risk analysis techniques used are subsequently compared and evaluated. The results are then assessed and a proposal for the use of virtual reality in practice is put forward.
