Abstract
An increasing demand for reducing cost and time effort of the design process via
improved CAE (Computer-Aided Engineer) tools and methods has characterized the
automotive industry over the past two decades. One of the main challenges
involves the effective simulation of a vehicle’s propulsion system dealing with
different physical domains: several examples have been proposed in the
literature mainly based on co-simulation approach which involves a specific tool
for each propulsion system part modeling. Nevertheless, these solutions are not
fully suitable and effective to perform statistical analysis including all
physical parameters. In this respect, this paper presents the definition and
implementation of a new simulation methodology applied to a propulsion
subsystem. The reported approach is based on the usage of Synopsys SABER as
dominant tool for co-simulation: models of electronic circuitry,
electro-mechanical components and control algorithm are implemented in SABER to
perform tolerance analysis; in addition, a dynamic link with engine plant model
developed in GT-SUITE environment has been established via a dedicated
procedure. Moreover, a HPC Grid (High Performance Computing Grid) is used with
the aim to execute simulations of long engine maneuvers as well as to
parallelize jobs while applying Monte-Carlo methods. The overall approach is
tested on the active thermal management subsystem of a General Motors internal
combustion engine in order to evaluate the robustness of control algorithm
against electro-mechanical part variation and software calibration settings.
