Abstract

In this paper, the magnitude of sled pulse and initial sled setting angle were reviewed to derive the sled conditions for reproducing occupant injuries from the Oblique Mobile Deformable Barrier Test in US NCAP. 72 crash simulation were performed using validated simulation model and experimental data. A meta-model optimization identified optimal conditions accurately reproducing the Brain Injury Criterion and chest deflection values. The injury tendencies remained consistent despite changes to the restraint system. As a result, cost-effective and repeatable sled test conditions for sled crash tests were derived.
