Crash Test Dummy
full-scale anthropomorphic test devices (ATD) that simulate the dimensions, weight proportions and articulation of the human body, and are usually instrumented to record data about the dynamic behavior of the ATD in simulated vehicle impacts
A crash test dummy is a test device (commonly abbreviated 'ATD') that is made to be close to the same shape, size, heaviness, proportions and articulation of the human body. They sometimes have equipment embedded in them that measures data about how hard things are hitting it and how fast the ATD is moving around. ATDs have many applications but are commonly used in simulated (test) car crashes to see how safe the cars are for people when they crash. There are many different kinds of dummies with different weights, for example, dummies that are the same size and weight as a baby.
