The New Modelica MultiBody Library

A new Modelica library for the modeling and simulation of 3-dimensional mechanical systems has been developed. It will be freely available in the Modelica standard library. Furthermore, the Dymola simulation environment has been considerably enhanced to support the needed features. The MultiBody library is first presented from a user?s point of view. Furthermore, all essential details of the implementation are described. The library includes features that are usually not available in other multi-body software, such as analytic handling of a large class of kinematical loops, or the arbitrary connection feature of objects. For example, series connection of 3D line force components is possible.
