Evaluation of DAMAGE Algorithm in Frontal Crashes 2023-22-0006
With the current trend of including the evaluation of the risk of brain injuries
in vehicle crashes due to rotational kinematics of the head, two injury criteria
have been introduced since 2013 – BrIC and DAMAGE. BrIC was developed by NHTSA
in 2013 and was suggested for inclusion in the US NCAP for frontal and side
crashes. DAMAGE has been developed by UVa under the sponsorship of JAMA and JARI
and has been accepted tentatively by the EuroNCAP. Although BrIC in US crash
testing is known and reported, DAMAGE in tests of the US fleet is relatively
unknown. The current paper will report on DAMAGE in NCAP-like tests and
potential future frontal crash tests involving substantial rotation about the
three axes of occupant heads. Distribution of DAMAGE of three-point belted
occupants without airbags will also be discussed. Prediction of brain injury
risks from the tests have been compared to the risks in the real world. Although
DAMAGE correlates well with MPS in the human brain model across several test
scenarios, the predicted risk of AIS2+ brain injuries are too high compared to
real-world experience. The prediction of AIS4+ brain injury risk in lower
velocity crashes is good, but too high in NCAP-like and high speed angular
frontal crashes.
