Abstract
Using MBS/FEM combined structures, the model-based strength and safety factors were derived for crankshafts at Audi. By combining simulation and test results highly accurate results were achieved and made it possible to come up with a good interpretation of the strength behaviour. This article examines various disciplines used in the crankshaft calculations. Based on detailed simulation calculations a deeper understanding of the dynamic load situation was achieved.
