Crash test dummy

Crash test dummies are full-scale replicas of human beings, weighted and articulated to simulate the behavior of a human body, and instrumented to record as much data as possible on accident variables such as speed of impact, crushing force, bending, folding, or torque of the body, and deceleration rates during a collision for use in crash tests. They remain indispensable in the development of new makes and models of all types of vehicles, from family sedans to fighter aircraft. This article focuses on the role of crash test dummies in preventing injury to automobile occupants.
