IMAGINARY - Crash Test Dummies - BeamNG disk
What crash dummies test, really what are they made of and how long have researchers use them to make safer cars on the road These advanced models have a rich history and a bit sleazy Indeed, the first Crash test dummies are not dummies at all - so how to develop this new technology we also ask, so we set up a round-up of crash test dummy and how it came to be.
A crash test dummy is an anthropomorphic test device DAE This is a fancy way of saying that the models closely mimic the size, shape, mass, stiffness and energy absorption of a real human being some facts about the crash test dummies todayвЂ.
A model that is fully equipped with sensors and measuring devices cost more than 200,000.
Automakers use crash test dummies for testing car safety devices such as air bags and seat belts.
These safety features are estimated to have saved 329,000 lives since 1960.
Is it true that first Test Dummies crash-Corpses were human.
Believe it or not, yes researchers used human bodies as crash test dummies because they most closely simulated a living human being, however, ethics and public opinion ruled this practice Not only that, but many Questions were raised about the validity of data and subjects represented the experience of a person in a car accident.
The researchers then used as the next generation of crash dummies Lawrence Patrick, a researcher at Wayne State University, itself strapped into a rocket sled and took hundreds of laps to test the rapid deceleration affects the human body itself and his team have also taken explosions blunt chest and face Patrick conceded testing hurt the other drawback is that the researchers could only use such force in human testing live However, the data itself and her students generated became the basis of mathematical models that shaped future crash tests.
After the crash tests has evolved to measure the auto crash survivability, the researchers tested with live animals Mainly, they used pigs because they could stand up in a car and had a similar internal structure man, but the obvious effect on the public, and the outcry of activists for animal rights, has these practices to an end as well.
Sierra Engineering Company invented the first crash test dummy 1949 Sierra “Sierra Sam” created in the image of an adult 95th percentile male USAF Sam used to test ejection seat aircraft using rocket sleds In over the next 48 years, Sierra Sam evolved into the model of modern crash test, “Hybrid III, ” which is designed as a 50th percentile male GM developed hybrid III in 1977 and twenty years later, it became the norm industry for Automatic hybrid III crash test was designed to measure the frontal impact in recent years, designers have created a new group of models together to test other types of impact as well.
SID Side Impact Dummy measures of a side impact, the second most common cause of serious injury in a crash.
BioRID designed to test rear impacts, especially if the automakers can improve the headrests and neck and reduce the incidence of whiplash.
CRABI child mannequin that is used for testing of child restraints, seat belts and airbags.
THOR The heir presumptive Hybrid III, due to a spine edge, pelvis and face, providing better data on the impact of the face Which Crash Test Dummies is.
The skeleton of a crash test dummy is made of aluminum and steel skeleton every six steel ribs and synthetic plastics to mimic a vinyl skin of the human chest extends on the skeleton Each model is rigged with advanced electronic tools that measure a range of effects on the human body acceleration, power electronics, researchers torque and deflection then take these data and crunch numbers to determine how to make cars safer.
How Crash Test Dummies crash testing and improving the safety car.
Times have certainly changed, and the cars we drive today are like spaceships relative to the motor start Since 1930, more than 15 people died per 100 million miles traveled in a car with these statistics in rise, automakers have begun to take a little heat and the research that has led to the development of our friend Sierra Sam and his descendants began by 2011, the major advances in vehicle safety as the search for dummy impact test generated, fatalities decreased automobile a person to 100 million miles traveled Thanks to these super sophisticated gluttons for punishment, as well as improving the safety training of drivers, car drivers and passengers are 15 times less likely to suffer a fatal car accident today.
Crash Test Dummies are really like people, crash, test, dummies.
