Abstract [en]

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.
