Differences in the Dynamic Responses of the Thor-NT and Thor-FT Dummies 2006-01-0676
The structural differences between the Thor-NT and Thor-FT dummies, which have been proposed as next-generation dummies for frontal crash tests, were examined and the differences in dynamic response were verified by testing. Tests were performed on a HYGE sled simulating a frontal crash at an impact speed of 56 km/h. The 3-point seatbelt plus air bag combination was adopted as the restraint mechanism.
Differences in characteristics of the two dummies in the neck, thorax, and abdomen were found by calibration tests. Test results showed that the variation in shape of the abdominal area of the pelvis generates some disparity in the flexion of the thorax and abdomen.
