Progress in the Mechanical Simulation of Human Head-Neck Response

  • M. P. Haffner
  • G. B. Cohen


A mechanical neck has been constructed which simulates ±Gx human head motion in the automotive crash environment. The present design simulates head motion in the sagittal plane by means of a two pivot model. Pre-loading torques, as well as linear and non-linear torque elements, can be accommodated at each pivot location. The proposed method of validation is the matching of displacement-velocity response of the head as predicted by a two degree-of-freedom computer simulation with existing human data. Simulations have been performed using Daisy sled volunteer data; comparisons of head angular displacements and angular velocities show favorable correlation.
