SIMPACK Engine Crank Train
SIMPACK ENGINE CRANK TRAIN is an add-on SIMPACK module bundling which enables an easy, quick, accurate and reliable model setup as well as the sophisticated analysis of engine crank train models.
SIMPACK ENGINE CRANK TRAIN is available in a BASIC and ADVANCED version. Model setup can be done using a parameterised and customizable SIMPACK crank train model database. Depending on the focus of application basic crank shaft multi mass trosional dynamics up to highly detailed and complex flexible crank trains with hydrodynamic bearings can be analysed. Verified models can be directly used in complete engine models with coupled timing mechanism and valve train interaction.
