Since a physical crash dummy is a manufactured product like any other, it is feasible to simulate performance with analysis (FEA) software. And they are loaded with sensors (44 data channels on the current front-impact standard, the Hybrid III) that record up to 35,000 items in a typical 100-150-ms crash. They have ribs, spines, necks, heads and limbs that respond to impact in realistic ways. Made from a variety of different materials, including custom-molded urethane and vinyl, they are based on true-to-life human dimensions. As a result, crash dummies for front-impact (“Hybrid”), side-impact (SID) and rear-impact (RID) are now in use.Ī single physical crash dummy can cost more than $200,000. But car manufacturers are now also legally obligated to certify the effects of crash events on the humans involved.

The addition of air bags, combined with a properly worn lap/shoulder belt, reduces driver deaths by 61% in a frontal crash, according to the National Highway Traffic Safety Administration (NHTSA).
#DUMMY CAR ACCIDENT SIMULATION SOFTWARE#
As computer-aided engineering software and computing resources rapidly advance, there is increasing emphasis being placed on developing ever-more-accurate virtual crash dummies.Įnergy absorbing crumple zones and other structural innovations do help protect occupants during car crashes. But physical test dummies are only a part of the process. Stapp became an iconic figure to us engineers at White Sands and Holloman AFB for subjecting himself to high-speed sled experiments on the Holloman test track in that bygone era.)Ī major challenge in the ongoing development of physical crash dummies is the need to reasonably represent how the human body responds in an automotive accident. The Stapp Car Crash Conferences started that decade and continue today as a venue to share information on the latest research for improving vehicle crashworthiness and occupant safety. John Stapp realized that more of his fighter pilots were dying in car crashes than from accidents in their hi-tech jet aircraft. The idea for the automotive crash-test dummy arose in the 1950s when U.S.
