DYNAMIC SIMULATION OF THE INTERACTION BETWEEN RACEWAY AND RIB CONTACT OF CYLINDRICAL ROLLER BEARINGS

摘要

The dynamic simulation of rolling bearings is a very capable tool for the investigation of rolling bearing behavior and the prediction of possible failures. This contribution presents a modeling method based on commercial MBS tools with self-developed contact calculation routines. This concept allows for a very detailed modeling of the different contacts in the bearing. A new calculation approach is introduced to include precise pressure calculations for arbitrary contact geometries, which extends the capabilities of the existing models, e.g. to the simulation of combined loaded cylindrical roller bearings including roller end-rib contact. The consideration of mixed friction effects is achieved with an established mixed friction model The required parameters are calculated based on real measured surface topologies. An exemplary comparison with experimental results shows a very good agreement between model and experiment in the full fluid film lubrication and mixed friction regime for both, raceway and rib contacts.
