Abstract

The specifications and integration of two new Modelica libraries is presented: The Powertrain Dynamics (PTDynamics) and the Engines libraries. The libraries enable the simulation and modelling of powertrain systems including their fluid dynamic; pollutant emission; mechanical and thermal performances in one simulation environment (Dymola); utilising the object orientated modelling language Modelica.

Two variants of the Engines library are presented: a Mean Value variant (MVEL) and a Crank Angle Resolved variant (CAREL).

Both the PTDynamics and Engines libraries make use of a new approach to modelling the mechanics that captures the full MultiBody effects of the Powertrain system without the computational cost of using the standard Modelica MultiBody library.
