Vibration model of a powertrain for real-time environment

Abstract

In the early phase of powertrain development it is becoming important to link test environments with virtual prototypes. The Acoustic Competence Centre ACC Graz and AVL List Graz introduce a method for the rapid calculation of torsional vibration excitations in engines resulting from gas and inertia forces. The example of an all-wheel powertrain is used to present object-oriented modeling options for further application in a “Hardware in the Loop” HiL environment.
