Investigation on adult occupant protection in car pole side impact using various material and thickness of side doors and B pillar

Abstract

In this paper the objective is to study the effect of the material and thickness of the side doors and B pillar on crashworthiness and the energy absorbed in order to select a proper material and an optimized thickness to approach a five-star car concept based on the Euro New Car Assessment Program (Euro-NCAP) testing Pole Side Impact. In this matter, four materials and five thicknesses have been chosen for the vehicle model and a total of twenty simulations have been conducted. The results showed that the best selected materials and thicknesses were high strength Steel 204M with a thickness of 1.2mm for side doors and O.65mm for the B pillar, however, it is important to note that this selection is to maximize the absorbed energy not necessarily to reduce the total weight of the vehicle.
