Abstract

Mechanically-driven systems often contain both fast and slowrotating parts. The fastest moving parts determine the simulation timestep size of such systems, which often leads to unacceptable simulationtimes. By separating the model in a slow geometrically nonlinear partand a fast geometrical linear part, simulation times become reasonable.The paper describes how the dynamic influence of the fast rotating partson the slowly moving parts can be derived. A special finite element,modeling the interface between the fast and slow moving parts, isdescribed. An application is presented.
