Comparison of head and thorax cadaver and Hybrid III responses to a frontal sled deceleration for the validation of a car occupant mathematical model 2001-06-0035
The responses of head and thorax of cadaver and Hybrid III were
compared using frontal sled tests. Four pairs of tests were
conducted at 50km/h. Two types of force-limiting belt were used.
Subject instrumentation included head and spinal accelerometers.
Following the tests, autopsies were performed. This research
provided complementary information concerning human behavior during
sled test. Local differences for the thorax and the head behaviors
between the two restraint systems were identified.
Considering new restraint systems, the comparison of behaviors
of the cadaver and the dummy indicates that improvements in the
thoracic and head dummy responses have to be made. The results of
this study will also be used as validation data for the development
of a new numerical model of a driver (HUMOS model - HUman MOdel for
