Crash Test Dummy (Chinese Anthropometric Data)
The Crash Test Dummy is designed based on Chinese anthropometric data and represents an average adult male (50th percentile). Its structure and functionality are similar to international 50th percentile dummies, featuring human-like form and biomechanical responses. It can serve as a surrogate for humans in frontal crash testing, measuring acceleration, force, moment, and displacement at key body regions including the head, neck, thorax, pelvis, thighs, knees, and lower legs. This dummy supports occupant safety research and injury analysis.
Application
The Crash Test Dummy is primarily used for:
(1) Frontal crash occupant protection testing;
(2) Verification of seat and seatbelt restraint systems;
(3) NCAP and new car assessment crash tests;
(4) High-repetition research and laboratory crash testing;
(5) Vehicle occupant injury analysis and biomechanics research;
(6) Performance evaluation of occupant safety systems in aerospace, rail, and other transport applications.
Standards
(1) GB/T 11551 – Protection of occupants in frontal and side collisions
(2) GB 14166 – Motor vehicle seat belts and restraint systems
(3) ISO 9790 / ISO/TR 9790 – Road vehicles – Side impact dummy – Evaluation method
(4) FMVSS 208 – Occupant crash protection
(5) FMVSS 214 – Side impact protection
(6) UNECE R94 – Frontal collision protection
(7) UNECE R95 – Lateral collision protection
(8) Euro NCAP – Frontal and side impact test protocols
