The 50th Percentile Male Side Impact Dummy represents an average adult male in terms of body size and mass. Developed based on AMVO 50th percentile male data, and optimized using multiple anthropometric databases covering different populations, this dummy provides high-fidelity biomechanical responses for side impact testing. Its design complies with ISO/TR 9790 evaluation procedures, and has been validated through 33 tests to assess its biofidelity, providing reliable data for vehicle side safety design and occupant injury protection research.
Application
The 50th Percentile Male Side Impact Dummy is primarily used for:
(1) Vehicle side impact occupant protection testing;
(2) Evaluation of B-pillar, door trim, and sill beam crashworthiness;
(3) Verification of side airbags and curtain airbag restraint systems;
(4) Safety development and regulatory certification for new or updated vehicle models;
(5) Occupant injury assessment and crash safety research;
(6) High-repetition crash data collection for research institutions and testing labs;
(7) International and regional NCAP (Euro NCAP, C-NCAP, U.S. NCAP, etc.) side impact tests.
