2-Door Vehicle Body Local Force Evaluation with the IIHS, EuroNCAP, and LINCAP Side Impact Barriers 2004-01-0333

Structure enhancement based on data monitored in a traditional side impact evaluation is primarily a trial and error exercise resulting in a large number of computer runs. This is because how the structure gets loaded and the degree of contribution of local structural components to resist the impact while absorbing energy during a side collision is not completely known. Developing real time complete load profiles on a body side during the time span of an impact is not an easy task and these loads cannot be calculated from that calculated at the barrier mounting plate. This paper highlights the load distribution, calculated by a procedure using computer aided engineering (CAE) tools, on a typical 2-door vehicle body side when struck by moving deformable barriers used in the insurance institute for highway safety (IIHS), EuroNCAP and LINCAP side impact evaluations. The interaction between each barrier and the subject vehicle provides insight to the local impact loading on a 2-door vehicle and help understand structural resistance to the impact.
