Abstract
When simulating manufacturing processes both, the kinematic behaviour of the machine tool structure and its elastic behaviour have to be taken into account.
The elasto-kinematic behaviour of machine tools can be calculated using the finite elements method. Alternatively, the machine tool structure can be modelled by a multibody system with extensions for elasticity modelling (hybrid multibody system).
In this paper a new approach for modelling elasticity within multibody systems is introduced — the Subelement Model. The calculation results of this model are compared to the calculation results of a finite element analysis on the basis of a simple structure with respect to accuracy. A further subject of research is the ability of the Subelement Model to model non-linearities (e.g. friction and contacts).
