| | Crash test dummy - Wikipedia, the free encyclopedia |
 | | Crash test dummies are full-scale replicas of human beings, weighted and articulated to simulate the behavior of a human body in a motor-vehicle collision, and instrumented to record as much data as possible on variables such as speed of impact, crushing force, bending, folding, or torque of the body, and deceleration rates during a collision. |
 | | The child models are very recent additions to the crash test dummy family; because so little hard data are available on the effects of accidents on children, and such data are very difficult to obtain, these models are based in large part on estimates and approximations. |
 | | When the dummy has been determined to be ready for testing, it is dressed entirely in yellow, marking paint is applied to the head and knees, and calibration marks are fastened to the side of the head to aid researchers when slow-motion films are reviewed later. |
