Creation and analysis of electrical machines parametric models at CAD systems.
Chmelíček, Petr ; Janda, Marcel (referee) ; Kuchyňková, Hana (advisor)
Aim of this bachelor’s thesis is to demonstrate facilities of computer aided design on practical tasks. First part contains description of Autodesk Inventor, which is one of the most important modern parametric CAD systems. There is described the basics of modeling, drawing creating and analysis of design. Second part is oriented on demonstration of capabilities of Ansys Workbench, which is important system for solution of engineering problems by the finite element method. Also there is description of user interface of Ansys, analysis of electromagnetic field in asynchronous motor and description of one phase asynchronous motor. Task of last part is to create animated presentation of asynchronous motor with outer rotor in Inventor studio.
Utilization of Inventor Studio for modeling, vizualization and animation
Kučera, Petr ; Vaněk, Jaromír (referee) ; Kuchyňková, Hana (advisor)
Software program Autodesk Inventor is described in bachelor thesis. The aim is the description of the options of module Inventor Studio and its use at manual process and creating of a simple model of the electrical equipment and creating their presentations.
Utilization of adaptive CAD systems at virtual model creation of electrical motors
Sedláčková, Petra ; Janda, Marcel (referee) ; Kuchyňková, Hana (advisor)
Thermal analysis of electric machine is one of the key steps in design procedure. Traditionally, thermal calculations are done by analytical method, mostly based on equivalent electrical circuit, where thermal quantities are replaced by equivalent electrical quantities. These methods employ so-called electro thermal analogy. Different approach is to use Finite Element Method, which is the main goal of this thesis. First part of the thesis is devoted to description of CAD system Autodesk Inventor, which is modern parametric CAD for modelling of virtual prototypes. This system is then used for creation of three dimensional model of brushless DC machine. Second part is focused on thermal calculations in Ansys Workbench environment. Model of brushless DC machine created in Inventor is transferred into Ansys Workbench and thermal analysis is carried out.
DC Motors Analysis and Innovation
Šimko, František ; Kuchyňková, Hana (referee) ; Hájek, Vítězslav (advisor)
The thesis aims to explain the design a prototype of an innovated small engine. It is divided into three main parts. The first part is focused on the analysis of low power DC small engines available on the market. The second part consists of measuring, construction and loss analysis of a DC small engine with permanent magnets. The last part deals with the possible innovations of a small engine with permanent magnets and subsequent implementation of some of them. The innovations are supported by calculations and simulations.
Modern CAD Systems in Power Engineering
Strnad, Karel ; Vorel, Pavel (referee) ; Kuchyňková, Hana (advisor)
This work is focused on the short summary of history CAD systems and there are described the news, which brings the new version of programme Autodesk Inventor compared to the previous one. Then, in five steps there is described the procedure of parametric modelling in the programme Autodesk Inventor, from the sketch to final 3D model, including the drawing documentation. The work put particular emphasis on the explanation the basic modelling functions and environment in the same programme. An important part of this work is also the short explanation of some concepts relating to parametric modelling and animation of the model created in programme Autodesk Inventor.
Utilization of thermal systems at power electrical engineering
Strnad, Karel ; Janda, Marcel (referee) ; Kuchyňková, Hana (advisor)
The main theme of the master's thesis is using of thermal camera to measure temperatures in electrical engineering. First are mentioned the physical principles of heat transfer. Then the thesis deals with methods of determining the correct emissivity of the measured object and in the next point with sensors designed for sensing infrared radiation, there is also part dedicated to evaluation software Report Sat Standard, which was used to evaluate the pictures taken with thermal camera SAT-HY 6800. Next part of this work is the measurement of the DC and EC motor with help of thermocamera, which took place in the electric company ATAS Nachod. Attachment to this master's thesis there is animation of EC motor created in Autodesk Inventor.
Computer aided design at electrotechnics
Tesař, Radek ; Veselka, František (referee) ; Kuchyňková, Hana (advisor)
This work deals with questions how to take advantage of modern technology for support purposes in the projection in electro engineering. It the introduction it informs about common bases of the projecting, purposes and grades of processed documentations. It is followed by the categorization and dividing types of software tools according to the purpose of use linked with the description of historical development of graphic systems, from raster to vector. In the end there is a practical show of documentation realization processed by a specialized instrument Astra92 Inc.
Diagnostic and improvement of electrical contact
Hrdý, Branislav ; Kuchyňková, Hana (referee) ; Veselka, František (advisor)
The aim of bachelor thesis is create a summary overview of terminals, to obtain information about contruction, materials of the conductive parts of the terminals and its snap methods. The next goal was description of methods of conductors’ construction and snap methods of its con-ductors. All processed information is obtained from the technical literature and from practical knowledge acquired during the measurement and monitoring of analyzed terminals. The final goal was to create an animated 3D model of terminal as a sample of main process of terminals’ working principle. In conclusion of this work is comparison of terminals, and their properties, facts observed during measurement or testing.
Chassis Electrical Systems
Slaběňák, Patrik ; Kuchyňková, Hana (referee) ; Hájek, Vítězslav (advisor)
Travelling by bus is very extended in present and safety return home is a wish of every passenger. Outcome of this bachelor work is a survey of the most used stability systems, used in cars and facilitating the work of drivers in critic situations. Among others, this work contains the survey of powers acting on a vehicle during the ride. This powers influence impending slippery road on aggravated adhesive conditions. Individual systems are described attentively and supplemented by illustrating pictures, which near this issue and facilitate the real idea of functionality. At the conclusion of this work is mentioned the theoretical suggestion for practical exercising of a subject automobile electrotechnics and also a referring is mentioned to my continuation in this dissertation.
Engine Motormanagement Software
Kuda, Roman ; Kuchyňková, Hana (referee) ; Hájek, Vítězslav (advisor)
Increasing requirements and claims on running of motor vehicles contributed to development of new systems on the mixture preparations of fuel and ignition. Cardinal causes, which led to the very intensive research and later introduction of superior systems of injection and ignition, where fulfilment of stricter emission limits, lower fuel consumption at prezent engine-power increase and engine torque. The conception of the classical gas-engine was not changed over the past few years. The supervising elements as ignition and injestions of engines are continuously changed.
