Professor raises concerns
about safety equity
Furthermore, recent studies by
the Centers for Disease Control
and Prevention also show that
obesity prevalence varies by
income and education status,
and the relationships are
complex and differ by sex and
race. Therefore, the projected
increase of older and obese
population in the U.S. and their
interacting effects on sex,
income and education further
motivate future efforts to
develop more advanced safety
designs for improving safety
equity and mitigating injuries in
these vulnerable populations.
New tools available
Over the past two decades, finite
element (FE) models of human
anatomy have become
increasingly accurate, with the
current state-of-the-art wholebody
models containing over 2
million elements. However, these
FE models have been
constructed to represent
approximately the same body
size and shape as the ATDs.
Therefore, they do not
meaningfully extend the ability
to consider physical human
variability in restraint
optimization. To overcome this
limitation, our research group
20
September 2023
Examples of occupant kinematics in U.S.-NCAP frontal crashes.
has developed a new parametric human body
modeling methodology that enables these complex
human models to be rapidly and accurately morphed
to represent any of a wide range of human body sizes
and shapes. This new capability provides, for the first
time, the ability to systematically consider the
influence of the occupant characteristics on crash
outcomes and to optimize vehicle safety technologies
for the entire population of users, not just for ATDs. n
ABOUT THE AUTHOr
Jingwen Hu, Ph.D., is Associate Director, Research Associate Professor
& Miller Faculty Scholar, University of Michigan Transportation
Research Institute. The 18-years SAE member co-chaired a session at
WCX 2023 dealing with occupant protection. Dr. Hu's research
interests primarily focus on impact/injury biomechanics in motorvehicle
crashes by a multidisciplinary approach using a combination of
experimental, computational and epidemiological procedures.
