FREE ABSTRACT (to read the full article, please log in below).
Light weight structures with high
structural performance are one of the most important goals for automotive
and transportation applications. One manufacturing technology, aiming to
enable low weight design, is the combined forming and quenching of tubular
thin-walled profiles of high strength steel. For optimal utilisation of
this technology it is necessary to simulate and analyse the processes involved
in a fast and efficient way. In this work, experiments of high temperature
bending of thin walled profiles are performed and the forming response
force is compared with results from finite element simulations. The analysed
forming is modelled as a constant temperature forming and the material
data for the specified temperature is evaluated from experiments and literature.
The simulations and experiments are conducted to study the ability of the
finite element model to predict high temperature forming characteristics
and simulate the influence of profile and tool geometry. The need for further
improvements and developments in the simulation technology is however identified.
This work is part of a research project LOWHIPS (Low Weight High Performance
Steel structures) aiming to obtain new knowledge concerning the involved
forming and quenching processes and how they will affect the performance
of the product.
