Crash Test Dummies - Mmm Mmm Mmm (Official Music Video)
Last week we showed you how the crash test dummies have evolved over the years Today we take a look where they run and how to re modern improvements do crash tests more reliable.
How we collect and interpret the crash test data has come a long way since the practice began in the 1950s, but the basics of how we perform in fact the tests haven t changed a dummy or sometimes a family of them loaded with sensors gets looped in a stripped car grease paint is often applied to the dummy's head, then the car is sent hurtling into a barrier or, in the case of side impact tests a barrier is sent hurtling in the car.
During the collision, paint fat dummy rubbed off on any surface it comes in contact with, indicating the risk of injury caused by airbag deployment.
The researchers then decrypt electronic records many load cell dummy sensors that convert impact energy into electronic signals and various other devices on different parts of the head of the body of the model, neck, chest, pelvis, legs, feet, etc. They also look to physical damage to the car video and examining the impact of a full picture of the accident This image eventually becomes a crash test rating.
A new crash test dummy called THOR, which has been in development since the 1990s, is expected to replace the current Hybrid III crash dummy test of choice for the National Highway Traffic Safety Administration NHTSA.
The biofidelity a fancy word to be realistic THOR is amazing head and neck model are designed with muscle strength so that they rotate as the head of a real human being and not as a rag doll has THOR also clavicles and a complete set of sensors lined coasts to give researchers a better understanding of how accidents affect the human thorax and continuous development, THOR react and look more like us.
But Thor is not just a pretty face filled with more than 134 channels of data more than 78 Hybrid III may also read all of the tension in the Achilles tendon during a collision with the force of a blow to the head in a frontal collision load in addition to sensors that measure the force of impact, sports THOR accelerometers, which record the post-accident acceleration on parts of the body.
While THOR hasn t quite made its way into the standard rotation of the fictitious list NHTSA, its development has certainly paved the way for the results of crash tests and more detailed virtual crash tests THOR is the future crash tests more realistic and greater vehicle safety.
THOR The God of Crash Test Dummies, thor, crash, test, dummies.
