Deformable Load Sensing Hybrid III Face

Recently obtained force-deflection information for the frontal, zygomatic and maxillary regions of the human cadaver head and the Hybrid III ATD head indicates need for a redesigned Anthropomorphic Test Dummy (ATD) face. A prototype, deformable, load-sensing face (DLSF) was designed, with human-like-force-deflection compliant materials. The face was divided into six load sensing segments. The force level and impact location as a function of time can be determined for each segment, as well as for a selected set of segments and the whole face. The prototype face underwent preliminary testing for comparison with available cadaver data.
