The performance and development status of experiment dummy for national aerospace dynamic experiment testing was introduced. The development task can be divided into four parts: the human body parameter measuring system, dummy mechanical structure system, data collection and processing system, and dummy reliability validation system. The emphasis was put on the description of material selection and structural design features of the skeletons, joints and skin of the dummy. The dummy sensing ability can output 64 channel physical signals, and the overall performance of the dummy is near to American military dummy ADAM. It can be used as an effective tool for dangerous dynamic experiment testing in aerospace domain.
