Crash Testing - Johns Hopkins Applied Physics Lab

In 2001, Mr. Cox performed 300 hours of biomechanical research and testing at the Johns Hopkins Applied Physics Laboratory in Columbia, MD. This study examined the changes in dynamic cervical loading forces in the Hybrid III, anthropomorphic crash test dummy, as the seat back was stiffened. The target change in velocity was 11.0 mph over 90 milliseconds. More than 40 tests were performed and as one might expect, the forces in the neck increased as the seatback was stiffened.
