Abstract

Four rigid barrier, frontal vehicle tests at 48 and 56 kph using the TAD-50M dummy were: performed. Restraint conditions included a 3-point belt only, an airbag only, and a combination bag and 3-point belt system. TAD-50M responses, including the head, chest. and pelvic accelerations, belt and femur loads and chest deflections have been analyzed and compared with the Hybrid III. Some user convenience issues related to the use of the TAD-50M in a test environment are also discussed.

The data from the four DGSP transducers on the TAD have been analyzed to study the differences in response of the TAD-50M thorax to loading from belt and airbag. The TAD—50M produced symmetric A-P deflections under airbag loading and asymmetric deflections under belt loads. For airbag tests, maximum deflections reached 70 mm, while for 3-point belt tests, maximum deflections reached 50 mm. Some lateral deflection was observed for all restraint cases, especially for the belt only restraint case at the higher impact speed. In addition, vertical deflection was also observed for the bag restraint tests. Deflection rates were generally higher for the bag restraint tests.
