SIMPACK Automotive

SIMPACK Automotive is an add-on SIMPACK module which enables an easy, quick, accurate and reliable model setup as well as the sophisticated analysis of mechatronic vehicle components and complete vehicle models (Handling, Ride, NVH, SiL, MiL, HiL).

With SIMPACK Automotive numerous specialised automotive MBS modelling elements can be used in order to build up detailed component models, complete vehicle models and according analysis scenarios. Furthermore SIMPACK Automotive contains a predefined, parameterised and customizable model database (substructures) which enables quick and easy model setup. This also enables definition and automated execution with postprocessing of standardised analysis scenarios. As a result of SIMPACK's open modelling structure and depending on the application focus, the versatility and range of analysis can be unlimited extended and combined with all other SIMPACK Add-on Modules, e.g. 3rd Party Tire Modules like TM-Easy, TNO-SWIFT, F-Tire, CD-Tire, Flexible Bodies, NVH, Elastomer, User, Control (SiL). As a matter of course, all SIMPACK models are completely compatible between each other.

Applications
