Abstract

This study investigated the ability of a number of different dummies and candidate injury criteria to correlate to retrospective real world data. Vehicles were chosen for their rate of soft tissue neck injury (STNI) claims in the field. The front seats of the selected vehicles were mounted on a HyGe sled and loaded with instrumented dummies. They were then subjected to a simulated rear impact using a bi-modal pulse of 16km/h delta V.

Correlation of the measured and calculated test results, especially the NIC, Lower Neck Extension Moment (-My_lower) and the newly proposed LNL-index (Lower Neck Load index), to claims frequency was investigated. In conclusion, good correlation with claims data was found using -My_lower with the Hybrid III and RID2 dummies. Similarly good correlation was found with the LNL-index when applied with the RID2 dummy. It should be noted that -My_lower and the LNL-index could not be investigated on the BioRID II, since no lower neck load-cell was available for this dummy at the time of testing.
