The dynamic dummy plays an important role in the research of protecting human beings from impact environment. To collect data from dummy in dangerous impact tests is the fundamental method used in developing protection equipment and systems in aerospace, automobile and other industries. The performances of a dummy depend on its simulation degree, as well as the quality and quantity of sampled signals. The dummy technology abroad is now indispensable in developing the protection of aviation ejection and rescue system, and also beneficial to automobile and other industries. China had no Chinese characterized dummy applied until the year of 2003 when the dynamic dummy was created in Institute of Aviation Medicine, and the dummy has equivalent high performance as that made by the United States and has been availably exerted in aviation. For evaluating the impact injuries on Chinese human beings, it is necessary to further develop Chinese characterized dummy series, and to establish the all-around criteria by strengthening application of digital virtual dummy in impact environment study.
