Crash test dummy

A crash test dummy is a full-scale anthropomorphic test device (ATD) that simulates the dimensions, weight proportions and articulation of the human body, and is usually instrumented to record data about the dynamic behavior of the ATD in simulated vehicle impacts. This data can include variables such as velocity of impact, crushing force, bending, folding, or torque of the body, and deceleration rates during a collision for use in crash tests. The more advanced dummies are sophisticated machines designed to behave as a human body and with many sensors to record the forces of an impact; they may cost over US$400,000.For the purpose of U.S. regulation and Global Technical Regulations and for clear communication in safety and seating design, dummies carry specifically designated reference points, such as the H-point; these are also used, for example, in automotive design.Crash test dummies remain indispensable in the development of and ergonomics in all types of vehicles, from automobiles to aircraft.
