Abstract and keywords

Generating a target for the quantitative assessment of crash dummy biofidelity based on normalized post‐mortem human subject (PMHS) response data is important for dummy design and development. Normalization is the process of modifying a set of PMHS response data to represent the response of a typical sized human, for example the 50th percentile male. A biofidelity target is the normalized response against which the response of a dummy is quantitatively compared. A mechanistic and statistically based viscoelastic methodology is presented for normalizing PMHS response data based on the applied force, the thoracic deflection and the deformation energy at maximum deflection. A force versus deflection biofidelity target is generated consisting of a mean response curve with a two‐dimensional standard deviation ellipse tolerance. This paper provides a detailed explanation of the method, application to an example data set and comparisons to previous methods of normalization using the ellipse coefficient of variation as a measure of similitude.

Keywords: PMHS, normalization, scaling, biofidelity, dummy
