Abstract

The forming properties and simulated side impact crash tests of two types of B-pillar reinforcements were analysed. The first B-pillar was drawn from simple blank made of dual phase steel DP600 with thickness of 1.2 mm. The second one was drawn from tailor-welded blank consisting of two dual phase steels DP600 and DP980 with thickness of 1.0 mm. The wall thicknesses in exposed areas of drawn parts were calculated. Both types of B-pillar reinforcements could by drawn without the cracks creation during the drawing process after optimization of blank holder forces. The simulated side impact crash tests showed similar reaction and deformation force values for both drawn parts and confirmed the same safety of B-pillar reinforcements made of tailor-welded blank as for the one made of simple blank.

Keywords: tailor-welded blank, dual phase steel, simulation, deformation force, reaction force
