Abstract

The objective of this study was to assess and compare the current lateral impact biofidelity of the shoulder, thorax, abdomen, and pelvis of the Q6, Q6s, and HIII 6-year-old anthropometric test dummies (ATDs) through lateral impact testing.

A series of lateral impact pendulum tests, vertical drop tests, and Wayne State University (WSU) sled tests, based on the procedures detailed in ISO/TR 9790 (ISO/TR 9790, 1999) and scaling based on known research of 50th -percentile male testing to the 6-year-old using Irwin et al. (2002). The data collected from the three different ATDs was filtered using SAE J211 (SAE J211- 1, 2003), aligned using the methodology described in Donnelly and Moorhouse (2012), and compared for each body region tested (shoulder, thorax, abdomen, and pelvis). In addition, the biofidelity performance for the three ATDs in lateral impact was assessed against the scaled biofidelity targets published in Irwin et al. (2002), as well as the abdominal biofidelity target assessment published in van Rantingen et al. (1997).

Preliminary results showed that the Q6s performed more closely to the outlined biofidelity targets than the Q6 or the HIII 6-year-old at all tested body regions. Even though the Q6s showed improved lateral impact performance, it did not meet all biofidelity targets. Future research is to be performed to evaluate the validity of the current 6-year-old lateral impact biofidelity targets based on the lateral impact testing biofidelity assessment of surrogates of appropriate size and weight.
