PERFORMANCE EVALUATION OF A THREE-YEAR-OLD CHILD TEST DUMMY

The objective of this research was to evaluate new Endevco Model 7267A triaxial accelerometers in the head and chest areas of a SA103C 3-year old child test dummy. The performance of the new accelerometers was compared to the original transducers, Endevco Model 7267C, in a series of dummy replicate calibration and dynamic sled tests performed with both type accelerometers. The Task I work entailed the calibration testing of the dummy with replicate impacts to the head and chest areas. With modified accelerometer mounts, all dummy performance measurements with the newer accelerometers were within 2% of the dummy data using the original transducers. The Task II work involved four 30 mph sled tests of two child dummies in a side-by-side configuration with the Model 7267A accelerometers in one dummy and the Model 7267C in the other. A comparison of these results indicated that the dummy performance levels with the newer transducers were generally within 5% of the data from the original accelerometers. For the one case of head peak resultant accelerations, when using GM Love seat restraints for the dummies, the data compared to approximately 9%.
