Crashworthiness determination of side doors and B pillar of a vehicle subjected to pole side impact

Abstract

Pole Side Impact Test is one out of three crash tests described by Euro NCAP standard for star rating of a vehicle and is required for assessing the Adult Occupant Protection. In this paper the goal is to determine the crash worthiness of side doors and B pillar in a Pole Side Impact Test based on Euro New Car Assessment Program (Euro-NCAP) using computer and simulation method. In this matter, a vehicle model has been prepared and meshed using Hypermesh and CATIA. The velocity of 29 km/h has been assigned to the vehicle which was on top of a cart while the pole has been assigned as a rigid static object based on Euro NCAP requirements specifically. Results show that different amounts of energy will be absorbed by each part, such as the side doors and the B pillar, and each part has a different effect on the crash worthiness of the vehicle in a Pole Side Impact Test. It can be concluded that to increase the amount of absorbed energy in a Pole Side Impact Test, the part which has more influence should be taken into greater consideration
