Design of the Modelica Library VehProLib with Non-ideal Gas Models in Engines / Designval av Modelica Biblioteket VehProLib med Icke-Ideal Gasmodell i Förbränningsmotorer

Andersson, Conny January 2015 (has links)
This thesis covers the reconstruction and the redesign of the modeling library VehProLib,which is constructed in the modeling language Modelica with help of the modeling toolWolfram SystemModeler. The design choices are discussed and implemented. This thesisalso includes the implementation of a turbocharger package and an initial study of the justificationof the ideal gas law in vehicle modeling. The study is made with help of Van derWaals equation of states as a reference of non-ideal gas model. It will be shown that for themean-value-engine-model, the usage of ideal gas law is justified.

Advanced concepts in Modelica and their implementation in VehProLib / Avancerade koncept i Modelica och deras användning i VehProLib

Montell, Otto January 2004 (has links)
<p>VehProLib is one of many libraries being developed for the object oriented multi-domain language Modelica. The layout and the current status of the library are shown. The aims of the library are to provide the user with a number of different components with different levels of complexity. The components included range from mean value engine components to in-cylinder models. An efficient way to handle parameters using records is provided. Different bus systems are implemented and discussed. Furthermore are replaceable fluid models introduced in the library. It will be shown that Modelica is a very efficient way to create an advanced modelling library.</p>
