Abstract

In low speed collisions, insurance cost is a factor which is taken into account as a design criterion to reduce structure damage and fixing cost. In this study, it is focused on the applied permanent damages of vehicle frontal door caused by pole impacts. In the side impact, the side door beam is responsible to absorb the most possible kinetic energy. Two significant parameters including material and geometry of a side door beam are discussed here to reduce permanent damage of the door. To study the effect of material as the first phase, six different sheets of material have been concerned to investigate the rigidity of the structure. For the second phase, geometry modification of the side door beam has been performed via creating new CAD-reinforcing ribs. Consequently, the strength in elasto-plastic mode, maximum deflection and plastic strain of the equipped system representing the permanent damage is obtained in order to achieve lower losses.
