Abstract
AbstractThe aim of this study was to develop an efficient and realistic numerical model in order to predict the dynamic response of the friction winder system. The absolute nodal coordinate formulation is an ideal approach for the modelling of friction winder systems. In this study, the rope was modelled as a planar beam element based on an absolute nodal coordinate formulation. The rope element allows the user to control the axial and bending stiffness through the use of two parameters. In this study, the interaction between the rope and the rotating drum is modelled using an elastic approach in which the contact is accounted for by the inclusion of a set of external forces that depend on the penetration between the rope and rotating drum. This made it possible for us to accurately predict the contact forces, including the stick and slip zones between the rope and the drum. Finally, the applicability of the friction winder model was presented and discussed.KeywordsFriction WinderAbsolute Nodal Coordinate FormulationFrictional ContactBeam Elements
