Model Stirlingova motoru v PSCAD

Abstract

Práca sa zaoberá návrhom Stirlingovho motora, pričom v úvode informuje o histórií a vzniku teploplynného stroja, popisuje elementárne časti a ich funkcie, približuje princíp činnosti vysvetlený pomocou termodynamického cyklu a porovnáva ideálny a reálny Stirlingov cyklus, a v neposlednom rade uvádza rôzne modifikácie s popisom ich odlišnosti. Matematický model Stirlingovho motora je spracovaný metódou Schmidtovej teoretickej analýzy a následne vytvorený v prostredí PScad v46. Postup tvorby modelu je uvedený v jedenej z kapitol práce a výsledky boli zohľadnené pri návrhu 3D modelu v prostredí Inventor Professional od Autodesk. Výstupom práce je zhodnotenie výpočtového modelu a jeho funkčnosti a dokumentácia k 3D modelu.

This dissertation about the Stirling engine deals with the history and formation of the heat engine. At the beginning of this work, fundamental parts and their functions are described, elucidating the principle of operation explained by the thermodynamic cycle and subsequently comparing the ideal and the real Stirling cycle and last but not least provides various modifications whilst describing their differences. The mathematical model of the Stirling engine is processed by Schmidth’s theoretical analysis and thereafter is created in PScad v46. The process of creating a model is shown in one of the chapters of this dissertation. The results were taken into account in the design of 3D models in Inventor Professional by Autodesk. The work concludes with the evaluation of the computational model and its functionality as well as the documentation of the 3D model.
