Production of a prototype casting of aluminium rotor with an insert using precision casting technology
Záviský, Matěj ; Jelínek, Radim (referee) ; Krutiš, Vladimír (advisor)
This thesis focuses on the production of aluminium castings with steel inserts produced by hybrid investment casting using additive technologies. The main objective is to analyse the production possibilities and quality of the casting, with emphasis on the shell cracking issue during high temperature firing of the model. The thesis deals with innovative techniques in investment casting and process optimization to achieve a strong metallurgical bond between materials. Bimetallic components can be used to achieve optimum application specific performance and structural integrity in various industry sectors. The use of digital technology and simulation software has also contributed to improving the final casting quality.

Transition State Simulation of Combustion Engine
Forbelský, Antonín ; Beran, Martin (referee) ; Svída, David (advisor)
Master's thesis focuses on the simulation engine transients. The model of single-cylinder engine was constructed in simulation software Lotus Engine Simulation. Then was made simulation of transients. The thesis try to describe the influence of moment of inertia of the engine, the engine starting speed and process of throttle opening during the transients. For all modes also compare two methods of fuel control.

Setting the parameters of the mathematical model of the Engine ECU
Vychopeň, David ; Beran, Martin (referee) ; Svída, David (advisor)
Master’s thesis is focused on creating a suitable methodology for determining the parameters of the electronic control unit of the engine. Discusses how the measurement of input data into the methodology, the basic description of its functions and display the resulting values. It includes evaluation of applicability of the methodologies and the real parameters when compared with the parameters established on the basis of established methodology.

Numerical Model of Engine Control Unit
Křepelka, Jan ; Beran, Martin (referee) ; Svída, David (advisor)
Master’s thesis deals with issues of controlling the amount of fuel injected by the control unit. Model of four-cylinder engine and computational model of control unit were constructed in the simulation software Lotus Engine Simulation. Then was made model checking of the control unit by simulation two transients (acceleration and shifting). In conclusion was made application a created model on the New European Driving Cycle (NEDC) and appropriately evaluated and processed the results of this simulation.

Thermo-physical parameters of exo-sleeves and their application in simulation programmes
Zajíček, Roman ; Kuzma, Zbyněk (referee) ; Roučka, Jaromír (advisor)
Thesis discusses exothermic sleeves. The first chapter briefly described the defects can occur during solidification. Further, there are provided methods for removing these defects. The method is described in detail using risers with an emphasis on the exothermic sleeves and thermo-physical parameters characterizing these sleeves. It also describes the influence of these parameters on the accuracy of computer simulations. In the final part of the work is done measuring of the real casting, which is then simulated in the Quikcast.

Model simulation using SIMIT
Váňa, Dominik ; Pásek, Jan (referee) ; Arm, Jakub (advisor)
This bachelor's thesis is focused on simulating a technological proces. The teorethical part of the text deals with the simulation tools available on the market. Special attention is paid to SIMIT tool, which is a complex solution for simulating processes. The thesis describes the basic control and the procedure of creation in this tool. The theoretical analysis presents the possibilities of its extension with additional libraries. It contains a brief description about these libraries, which provide much more simulation options. SIMIT is a virtual commissioning tool, a process design approach that is used to simulate a virtual factory model, test it, and debug it before it is deployed. This is a cost-effective and timesaving approach. In the practical part of the thesis two simulators were created with the SIMT tool, each of which simulates an excercise from the subject „Programmable logigs controllers“ (BPGA). The thesis presents model schemes of simulated processes that replace the real physical model. The results of the work are the created simulators, descriptions of their operation and valuation of their features and the properties of the SIMT program itself.

Vzdušný hokej - machine vision and game strategy
Sláma, Ondřej ; Lang, Stanislav (referee) ; Matoušek, Radomil (advisor)
The aim of this diploma thesis is to implement a robotic air hockey table in cooperation with the work of Dominik Jašek [37] . Specifically, the work deals with the implementation of simulation software that models behavior of robotic air hockey table, designing a game strategy for the robot and detecting position of a puck situated on the playing field. In addition, the work was extended by integrating said software modules under one control application and creating a user interface for controlling and managing all the functionalities of the robotic table through a capacitive touch screen.

GateCycle simulator and its applications
Svoboda, Adam ; Ťok,, Pavel (referee) ; Jegla, Zdeněk (advisor)
Hlavná náplň tejto práce je oboznámenie so softvérom GateCycle od spoločnosti General Electric a jeho následná aplikácia na simulovanie industriálneho parného kotla produkujúceho 120 t pary za hodinu. Dizajn práce je vo forme výučbového materiálu, ktorý môže byť použitý vo výuke predmetu procesného inžinierstva zameraného na simulačné softvéry. Prvá časť práce je venovaná krátkej teórii o simulačných softvéroch a uvádza niekoľko najznámejších procesných inžinierskych simulačných programov. Druhá časť je napísaná formou GateCycle manuálu. V krátkosti predstavuje pracovné prostredie a rozhranie softvéru, demonštruje ako vytvoriť a spustiť simulačný model, zadať vstupné dáta a vytvoriť reporty. Tretia časť práce je praktická, vybraný industriálny parný kotol je prezentovaný a následne je vybudovaný jeho simulačný model. Táto časť je vytvorená vo forme príručky „krok za krokom“ vysvetľujúcej ako vytvoriť model kotla a aké dáta boli zadané do jednotlivých procesných aparátov. Kotol je simulovaný v 3 režimoch, využívajúc zemný plyn, ťažký vykurovací olej, či dechtovú vykurovaciu zmes ako palivo a je prevádzkovaný za mierne rozličných procesných podmienok. V závere sú vypočítané spotreby paliva porovnané s reálnymi prevádzkovými dátami a je vyhodnotená presnosť výpočtov softvéru GateCycle v týchto konkrétnych prípadoch.
