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. |

Stiffness matrices
Advantages:
- suitable for simulations around the bearing operating point
- influences of the degrees of freedom on each other are modelled well (coupling terms are considered)
Disadvantages:
- nonlinear behaviour is not modelled
- bearing clearance is not considered
