A crash test dummy, or simply dummy, is a full-scale anthropomorphic test device (ATD) that simulates the dimensions, weight proportions and articulation of the human body during a traffic collision. Dummies are used by researchers, automobile and aircraft manufacturers to predict the injuries a person might sustain in a crash.[1] Modern dummies are usually instrumented to record data such as velocity of impact, crushing force, bending, folding, or torque of the body, and deceleration rates during a collision.[2]
Prior to the development of crash test dummies, automobile companies tested using human cadavers, animals and live volunteers.[3] Cadavers have been used to modify different parts of a car, such as the seatbelt.[4] This type of testing may provide more realistic test results than using a dummy,[5] but it raises ethical dilemmas[6] because human cadavers and animals are not able to consent to research studies. Animal testing is not prevalent today.[7] Computational models of the human body are increasingly being used in the industry and research to complement the use of dummies as virtual tools.[8][9]
