Extension of a Simulation Model of the Freeform Bending Process as Part of a Soft Sensor for a Property Control

This work introduces an Abaqus CAE simulation model and its validation for freeform bending with movable die, which is extended in the of a weld seam longitudinally welded tube. The superordinate goal development soft sensor, that can derive mechanical properties bent tube as basis closed-loop control. To guarantee close monitoring properties, sensor needs to be able extrapolate spatially. Because investigated steel tubes are welded, depicts disturbance regarding rotational symmetry. In developing validating numerical process, quantitatively describes influences has on significant improvement qualitative quantitative prediction achieved. modelling done based tensile tests material taken from seam, where hardness measurements then used local model. validated now provides time well cost efficient way primary investigation especially strength input data feed forward control machine. Therefore, this represents important addition property-control die.
