GAMING

DaimlerChrysler (Mercedes-Benz Car Group, Department of Power Train Simulation), has chosen SIMPACK software for multibody simulation. The decision to use SIMPACK was based upon a three year in depth software evaluation in the area of engine dynamic simulation. New SIMPACK software developments, resulting from a close collaboration between INTEC, the developers of SIMPACK, and Daimler Chrysler were also an important aspect of the evaluation. The decision to conduct a software evaluation and switch to SIMPACK was taken by Daimler Chrysler because: - The mechanics of complete engines, including all inter connections, is extensively analyzed and simulated at DC. - Therefore the best available MBS solver performance and accuracy for this demanding task was chosen. - A suitable software partner, which is dynamic and has short reaction times to demanding innovation requirements is also indispensable. - Processes and interfaces (e.g. FEM, EHD, etc.) which are both flexible and verified are essential within the MBS simulation solutions. - The chosen software must guarantee to be able to remain at the forefront of MBS simulation technology (e.g. Fatigue, NVH, etc.). Detailed evaluation and software development was carried out in the following areas: - Component models (dynamic valve spring, HLA, gear wheel, flexible contact, EHD, etc.) - Single valve mechanism - Complete valve train models - Timing mechanism (chain and gear) - Coupled complete systems (valve train – timing mechanism - crank train) - New developments in SIMPACK were jointly specified by DC and INTEC. The developments were implemented by INTEC and subsequently verified by INTEC and DC with measured data. The operative application of SIMPACK at Daimler Chrysler (Mercedes-Benz Car Group, Department of Power Train Simulation) began on January 1st 2006.
