Abstract:

An improvised SOM-LA/TA biodynamics model has been developed for the Hybrid II Anthropomorphic Test Dummy (ATD). This improved model more accurately predicts the HIC and lumbar load of an ATD subjected to the dynamic tests specified in FAR Part 23.562.b(l) & (2). Then dynamic tests were conducted at the Impact Dynamics Laboratory at National Institute for Aviation Research at various deceleration loads of 14, 19, 25 and 32 g's. The effect of the occupant size on the response of a seat/ occupant/ restraint system was studied by the construction of a few non-standard occupant data bases. In an effort to improve the head injury protection for passengers seated behind interior walls in transport aircraft, a head strike test apparatus was designed and constructed. Preliminary tests were conducted to evaluate Head Injury criteria (HIC)using the head component tests. Suitable energy absorbing padding materials were identified using both analytical and experimental measures. Guidelines were also developed for design and development of infant and child seats and restraint systems. Finally, recommendations for further improvements and research to be carried out is discussed.
