Abstract

This paper describes the results of laboratory evaluation of the thoracic assessment device (leased out by NHTSA under the cooperation research) developed for the advanced anthropomorphic test device and prototyped for the SOth percentile male dummy (TAD 50M) in a HYGE test under relatively severe impact conditions. The advanced thorax has been integrated with the HY-III head, neck, pelvis, and upper and lower extremities. The evaluation program consisted of eight sled tests; five at 30 mph and three at 35 mph, including airbag only, the 3-point seat belt and the 3-point seat belt with airbag systems using a white body of a compact car. The evaluation of the TAD—50M, judged by the comparison with HY-III, in terms of response characteristics found under this study are as follows.

HIC of the TAD—50M tends to be smaller than that of the HY-III, due to the difference in spine structure (Thoracic Spine Articulation) which would affect the dummy behavior.
Differences in deflection among individual sterna and lower ribs, and between right and left sides, can be measured by using the new thoracic displacement measurement devices. Owing to the above, various types of occupant restraint systems can be evaluated more precisely by using the new thoracic structure.
The practical applicability of TAD-50M as a human surrogate would be improved if the difference in shoulder behavior and head behavior of the TAD SOM from those of the HY-III could provide so called "biofidelity".
