Flexibility Effects in Multibody Systems

This paper summarizes procedures for studying flexible multibody systems using finite segment modelling. In these procedures flexible members of multibody systems are themselves modelled as multibody (or “lumped”) systems. The flexibility is then modelled by springs and dampers between the bodies. Although the method has the disadvantage of being computationally intensive, the procedures presented are intended to ease the computational burden by efficient modelling and by efficient analytical formulations. It is believed that this approach combined with finite element and modal analysis methods can provide a comprehensive global and local analysis. Two examples are presented.
