![]() ![]() ![]() ![]() There is a constant need for new testing because each new vehicle has a different design and as technology changes ATDs must be developed to accurately test safety and efficacy. Computational models of the human body are increasingly being used in the industry and research to complement the use of dummies as virtual tools. This type of testing may provide more realistic test results than using a dummy, but it raises ethical dilemmas because human cadavers and animals are not able to consent to research studies. Cadavers have been used to modify different parts of a car, such as the seatbelt. Prior to the development of crash test dummies, automobile companies tested using human cadavers, animals and live volunteers. 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. Dummies are used by researchers, automobile and aircraft manufacturers to predict the injuries a person might sustain in a crash.
