The 50th Percentile Male Crash Test Dummy is a biomechanical surrogate designed for frontal automotive crash testing. It is based on anthropometric data, body mass distribution, and joint characteristics of the 50th percentile adult male in European and American populations. The dummy accurately simulates the mechanical response of a medium-sized male occupant during collisions. It is widely used in regulatory testing, NCAP evaluation, and passive safety system development, serving as a core tool for frontal occupant injury assessment.
Application
You can use the 50th Percentile Male Dummy in the following applications:
Frontal occupant protection testing for passenger and commercial vehicles
Seatbelt restraint performance and injury evaluation
Analysis of frontal airbag deployment characteristics and protection effectiveness
Assessment of dashboard, steering, and pedal impacts on occupants
NCAP frontal crash testing for new vehicles
Human impact studies in aerospace, high-speed rail, military, and special equipment
Biomechanical research in universities and third-party testing institutions
