Comparison of the Six-Year-Old Hybrid III, Part 572 and TNO P6 Child Dummies 962437

The performance of three different six-year old dummies, the new Hybrid III six-year-old from First Technology Safety Systems, the Part 572 Subpart I and the TNO P6, was compared in a series of HYGE sled tests. The dummies were tested on aftermarket booster cushions in a Volvo 850 sled buck.
Two different sled pulses were used: a Volvo 850 30 mph frontal crash pulse and an ECE R.44 pulse. The behavior of the dummies was compared for these two sled pulses.
Motion analysis from high speed film was performed, showing the trajectories of the dummy heads.
All dummies were fitted with triaxial accelerometers in the head, chest and pelvis. The Hybrid III was also equipped with a chest deflection transducer and Denton six-channel upper neck and five-channel lumbar spine load cells. The signals from a number of these sensors were compared.
