Bridging the Gap: Development of frontal crash mode ATD Analogous human body models.

Anthropomorphic variation is an important factor in computational studies using Human Body Models (HBMs), particularly regarding how such differences can influence observed kinematics and loading. Currently, a gap exists between Anthropomorphic Test Devices (ATDs) and human body models (HBMs). By necessity, there are differences in constitutive behaviors at a material level, however segment mass distribution and anthropometry differences can make matched simulations of ATDs and HBMs difficult to interpret, which has real-world implications for current or future regulatory applications.

Development and preliminary validation of computationally efficient and detailed 50th percentile female human body models.

Objective: No vehicle testing standard (physical or computational) employs a mid-sized female human surrogate, despite discrepancies related to injury outcomes for female occupants amongst all vehicle users. We detail the design and preliminary validation of 50th percentile female (F50) computational human body models (HBMs) based on Global Human Body Models Consortium (GHBMC) models.

Method: Data for the target geometry was collected as part of the initial generation of GHBMC models.

Age targeted human body models indicate increased thoracic injury risk with aging.

Objective: The objective of this study is to generate age targeted versions of the male and female Global Human Body Models Consortium (GHBMC) occupant human body models (HBMs), to validate each in frontal impacts, and to assess rib fracture probability of each.

Methods: Six age targeted models were developed based on the GHBMC average male and small female occupant models (M50-O v6.0 and F05-O v6.
