The increased risk of injury in car-crash among the aged population highlights the need for improved assessment of safety systems. This study presents a new hybrid Morphing-CAD methodology that successfully creates finite element human body models with representative geometry of the aged population, demonstrating similar kinematic response in testing.
The aged population has been associated with an increased risk of injury in car-crash, creating a critical need for improved assessment of safety systems. Finite element human body models (HBMs) have been proposed, but require representative geometry of the aged population and high mesh quality. A new hybrid Morphing-CAD methodology was applied to a 26-year-old (YO) 5(th) percentile female model to create average 75YO and subject-specific 86YO HBMs. The method achieved accurate morphing targets while retaining high mesh quality. The three HBMs were integrated into a side sled impact test demonstrating similar kinematic response but differing rib fracture patterns.
