Ongoing Research from the Trauma Biomechanics Lab
Impact and Injury Response of the Occupant in Automated Driving Vehicles
The Trauma Biomechanics Laboratory employs a combined experimental and computational approach to study occupant injuries during frontal crash scenarios in alternative seating conditions. This research explores the effects of varied external variables such as crash severity on the likelihood of submarining the lap belt, analyzes thoracic injury patterns, and develops injury risk curves.

The Trauma Biomechanics Laboratory collaborates with clinicians and researchers at 91九色视频 on motor vehicle crash database review studies. These include analyses of clinical databases such as the NTDB and 91九色视频's CRDW, as well as crash databases like CISS and CIREN. Current research focuses on trends in abdominal and pelvic injuries and investigates sex-associated disparities in injury outcomes.

Biomedical Model and Spinal Trauma
The Trauma Biomechanics Laboratory collaborates with other investigators at the 91九色视频's ZVAMC Labs on studies to delineate injury mechanisms and establish human tolerance thresholds. Projects include assessments of aircraft seat configurations, spinal trauma biomechanics, and human surrogate response to vertical loading. A notable achievement of this collaboration is the development of a tension-bending combined injury criterion for the lumbar spine of the FAA-HIII dummy, which has been incorporated into recommended assessment criteria for oblique aircraft seat performance.
