BEARINX-MAP – Modelling of rolling bearings for MBS
![]() |
Current developments in hardware and, above all, in software tools make it possible to simulate increasingly complex models with an increasing level of detailing. The design of complete systems requires a good knowledge and understanding of the individual components and their interactions. |
What do you need in order to use BEARINX-MAP?

A simulation and the associated model are always an abstraction of reality. The decision on a particular abstraction level and a specific modelling requires a good understanding of the actual system. A complex model does not automatically constitute a correct model and a simple model is not always an inferior one. The decisive factor here is the newly acquired knowledge relating to the actual system. There are several possibilities for modelling a bearing using multi-body simulation. |
