The Hybrid III 50th Percentile Pedestrian is a Hybrid III Automotive Crash Test Dummy modified in the lower torso and knee regions for testing automotive-pedestrian impacts. The Hybrid III (Part 572 Subpart E) has greater biofidelity and instrumentation capability than the Hybrid II Pedestrian based on Part 572 Subpart B, deleted from Part 571.208 Sept 1997.
Non-automotive applications for this test dummy include equipment and injury potential studies of recreation vehicles, wheel chairs, medical equipment and sports gear.
The size and weight of the 50th Percentile Male Pedestrian Test Dummy represents an “average” of the USA adult male population. This dummy design incorporates the ranges of motion, centers of gravity and body part weights defined by the Society of Automotive Engineers’ anthropometric studies to simulate those of human subjects.
- Anthropomorphic one-piece cast aluminum skull and one-piece skull cap, have vinyl skin. Skull cap is removable for access to head instrumentation.
- Rubber and aluminum segmented neck has anthropomorphic angle versus moment response in dynamic flexion (forward bending) and extension (rearward bending) articulations.
- Cable through axis of neck limits stretching, controls responses and increases durability. Two-piece aluminum clavicle and clavicle-link assembly has cast integral scapulae to interface with shoulder belts.
- Six spring steel ribs with polymer-based damping material approximate human chest force-deflection characteristics. Each rib comprises left and right anatomical ribs in one continuous part open at front and anchored to back of thoracic spine. Sternum assembly connects front of ribs and incorporates slider for chest deflection transducer, which is standard and measures rib cage deflection relative to spine.
- Knee slider mechanism is removed yielding knee joint with rotation only.
- Straight lumbar spine replaces curved spine in automotive dummy allowing erect posture.
- Steel tube leg assemblies are covered with vinyl foam and vinyl skin. Lower legs and feet are interchangeable with instrumented versions.
- Constant friction movable joints need fewer adjustments and provide consistent flexion and extension articulations.
- Options include pelvis, neck shield and deformable face.
- Steel skeletal components with some aluminum and bronze joints
- Solid vinyl head skin and cap
- Butyl rubber neck
