General Motors has long been a pioneer in developing crash test dummies, including the Hybrid III model widely used today. But after years of building dumb dummies, the automaker is building smart dummies.
GM said its new dummies feature 70 to 80 sensors that
“We design these test dummies so that they mimic real life,” said safety engineer and Technical Fellow Jack Jensen. He runs the GM Anthropomorphic Test Device lab. “Data from the dummies helps us predict the risk of injury in a real crash. The more realistic the dummy, the more accurate the test results.”
The network of sensors installed in each dummy tells the engineers how much and what kind of forces the dummies endure during crash tests. The information, gleaned from physical tests and computer sims, helps the engineers understand how a vehicle, its safety systems and its occupants interact and respond during a crash.
Each dummy can cost as much as $500,000, according to General Motors.
