Abstract
The Hybrid III, which is the only universally used frontal crash
anthropomorphic test device, lacks a biofidelic abdomen that can be
used for different loading surfaces and loading rates. The
Frangible Abdomen, developed by General Motors Corporation in 1989,
is the only commercially available, dynamically tuned insert. While
the Frangible Abdomen has biofidelity under belt loading
conditions, it has neither the loading rate sensitivity nor the
appropriate mechanical response (biofidelity) for assessing injury
from non-belt impacts (e.g., airbags or steering wheels). A
loading-rate-sensitive abdomen that is also capable of assessing
injury is currently under development by the General Motors Safety
Research Department. In order to develop such a device, it is
important to identify the frequency and severity of injury to the
various regions and organs in the abdomen to prioritize their
instrumentation with the appropriate sensors.
In this study, crash data collected between 1988 and 1994,
contained in the database of the National Automotive Sampling
System (NASS), were analyzed to identify the frequency and severity
of injury to the abdominal organs in frontal crashes. Results are
summarized and compared with previously published studies.
