Klaus Tietzel, Thomas Hahn, Schaeffler Technologies AG Co. KG | CUSTOMER APPLICATION Enhanced Modeling of Rolling Bearings Current developments in hardware, and particu- larly, in software tools, make it possible to simu- late increasingly complex models with an ever increasing level of detail. The design of complete systems requires an in-depth knowledge and understanding of the individual components and their interactions. Depending on the key perspectives involved in the simulation, it is appropriate to allow the selection and definition of the degree of detail in the complete model and the subsystems. At Schaeffler, work has been carried out for years in order to develop and apply rolling bearing models and calcula- ® tion tools such as BEARINX .
