Abstract: The challenge in realization of factories of the future closely relies on advancement in flexible and adaptive forming processes. The aim is to enable robot systems to adapt their processes and planning parameters to different components and semi-finished product geometries without additional programming. In this context, the German Aerospace Center in Augsburg has developed an automated draping effector which is capable of picking up dry fabric cut-pieces, draping and positioning them in the double curved moulds. The special feature of this gripper system is the deformability of the gripper surface. To ensure a reliable and high-quality draping process, the correct gripping intensity of multiple suction pressure units and the positioning of actuators must be optimally selected for each given part and fabric. The determination of these (total of 145) parameters by physical tests using the "try and error" principle is simply not feasible due to high time and cost requirements. For this reason, a simulation process was developed at the Composites Research Network, which on one hand maps the mechanical behaviour of the gripper robot as a multi-body simulation and on the other hand it includes the fibre behaviour during draping with the aid of a FEM simulation with user-defined fabric model.
