ATD Neck Tension Comparisons for Various Sled Pulses
The structure of the racecar has been the subject of much discussion with regard to crash safety. The stiffness of the structure, the amount of crush and the resulting deceleration were being judged, in some instances, as too stiff or not stiff enough for the driver. Much of this discussion centered on crash incidents for which no deceleration data were available from crash recorders (black boxes). In this paper, crash test dummy (Anthropomorphic Test Device ATD) results are compared for various idealized deceleration-time histories (deceleration pulses) that represent various structural crush characteristics. A crash velocity of 64.4 KPH (40 MPH) against a wall was used to represent a life threatening energy level.
