Investigating the Multibody Dynamics of the Complete Powertrain System
Alessandro Picarelli, Mike Dempsey · Linköping electronic conference proceedings · 2009
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.
