AN EVALUATION OF PROTOTYPE SEATS USING BIORID-P3 AND HYBRID III WITH TRID NECK

Open publisher page 7 citations

Abstract

There has been some discussion on whether Hybrid III can accurately evaluate the risk of low-severity neck injuries in rear impacts because it has been developed for the evaluation of frontal impacts. A new dummy with an articulated spine and a flexible torso has been developed. The newest prototype, BioRID P3 has been compared with volunteer data at delta V (velocity change) 9 km/h and it was found to respond with a good biodidelity. The object of this study is to clarify the difference of response between the BioRID and the Hybrid III from tests using prototype seats at delta V 15 km/h. The characteristics of human kinematics which were confirmed in lower speed BioRID tests were also confirmed at delta V 15 km/h. The upper neck shear forces and moments and Neck Injury Criterion (NIC) of the BioRID were significantly different from those of Hybrid III. (A) For the covering abstract of the conference see ITRD E206422.
