Crash Test Dummy is generally composed of bones made of metal and silicone and foam materials covering the surface of the bones. When making the Crash Test Dummy, great attention was paid to making it bio-fidelity, that is, it strives to be the same as the human body in terms of shape, size and mass distribution, and the motion characteristics of the collision are the same as that of the human body.

The Crash Test Dummy is equipped with sensors that measure data such as acceleration, angle, force, bending moment, and displacement necessary for judging damage. Take C-NCAP as an example. An ordinary qinsun 50% dummy generally needs to collect as much as 26 sensor data.

Since the Crash Test Dummy is used in the vehicle certification test, the Crash Test Dummy must meet the necessary conditions of repeatability and reproducibility that can feedback the same response in the same test (same test environment). This has to mention the "calibration" of Crash Test Dummy. Before the car crash test, engineers must perform standard compliance verification on certain parts of the dummy's body, referred to as "calibration".

Crash Test Dummy is divided into many types according to the type of crash test and the size of Crash Test Dummy. The frontal Crash Test Dummy (qinsun, THOR) is used for frontal collisions, and the side Crash Test Dummy (ES-2, WorldSID, SID IIs) is used for side collisions. In a collision between an airbag and a car door, the smaller the physique, the greater the damage suffered. Therefore, in addition to 50% of the standard size members (AM50), experiments should be conducted on 5% of women (AF05) and children. Small female dummies (qinsun AF05) and child dummies are used in frontal collisions under the Chinese New Car Evaluation Regulations (C-NACP) and the US Federal Motor Vehicle Standards (FMVSS 208) and other regulations.
