Introduction
Library PowerTrain is a licensed Modelica package providing 1-dimensional rotational mechanical components
for vehicle power trains. It is also useful in general for modeling of gear boxes. The library
includes from easy to use to very sophisticated components to model power trains. It does not supply components
for all specific needs. But, all components are open and can be modified or extended by the user.
How to use this Library
You should be familiar with Dymola and Modelica in order to use this package. PowerTrain Library version
1.0 needs Dymola version 5.0a or later. Note, that the terms ”package“ and “library” are used interchangeably
in this tutorial.
• Running a Demo Model (cf. Section 2) helps you with a quick start and gives a useful introduction
to understand the concept of the library.
• Build a first Model gives a short step by step introduction for building a first model.
• Model DriveLine (cf. Section 4) combines the main components (engine, transmission, axle, resistance,
driver) of a power train. For most of these components different variants can be used including
your own versions.
• Basic Components (cf. Section 5) to build the main components (also useful for users building
higher level components).
• Concept of the Signal Bus (cf. Section 6) explains the concept of the signal bus that is used to
transport data between all components.
• Concept of the Animation (cf. Section 7) describes, how animation is set up and used.
• Description of all Demo Examples (cf. Section 8) describes the available demo models.
• Upgrade ((cf. Section 9) models that have been developed with a former version of the PowerTrain
library, e.g., with version 0.98.
• Literature (cf. Section 10) contains a list of useful books and literature.
DriveLine and Main Components
On the first hierarchical level of the PowerTrain library the main sublibraries are present, as well as the
main components for the first setup of a general powertrain: Bus, Driver, Engine, Transmission, Axle and
CarResistance. For all these components different variants exist (e.g., a specific 4- and 6-gear automatic
transmission). Additionally, model DriveLine is a complete drive line with these components. All available
variants, including user supplied variants, can be selected in the DriveLine model. To understand the
concept, open model “DriveLine” from the top level of the PowerTrain Library.
