Comparison of Kinematic and Thoracic Response of the 5th Percentile Hybrid III in 40, 48 and 56 Km/H Rigid Barrier Tests

Full-scale crash tests were conducted to investigate the correlation between the 5th percentile Hybrid III dummy kinematics and chest response at three test speeds. A total of 20 comparative full frontal rigid barrier tests were conducted at 40, 48 and 56 km/h with the dummies placed in the front and rear outboard seating positions. As test speed increases to 56 km/h, the forward excursion and rotation of the thorax increases significantly. This rotation combined with chest jacket distortions inhibits the accurate measurement of chest deflection. The influence of the seat characteristics and belt geometry at peak load are explored. A new multi-point sensing device, known as the RibEye is introduced in full-scale rigid barrier tests to evaluate the role of multi-point sensing in enhancing the accuracy of chest deflection measurements. This new instrumentation may significantly reduce the sensitivity to belt placement associated with traditional single point measurements. An impulse calculation method to evaluate the load management capability of restraint systems is proposed.
