ESTABLISHMENT OF THE REPEATABILITY OF PERFORMANCE OF THE SIX-YEAR-OLD CHILD TEST DUMMIES

The objectives of this research were to review the technical drawings of the SA106C six-year-old child dummy for adequacy of detailed specifications, to inspect the four dummies to make certain that their fabrication conformed to the technical drawings, and to determine, in replicate tests, the levels and variability of performance measurements obtained in calibration tests and simulated impact tests. Following dummy inspection, they were tested in a series of static and dynamic component tests in accordance with the test procedures specified in the Part 572 Subparts B and C. A series of 30 whole-dummy performance tests was then conducted on a HYGE accelerator sled with each dummy tested in a sequence of three replicate runs in three different child restraint configurations. The sled test configurations consisted of a child booster seat with lap and torso straps, a standard three-point automobile restraint harness, and a lap belt only configuration. The sled impact velocity was 30 mph. The primary measures of dummy sled test performance analyzed with the statistical methods were: (1) head peak resultant accelerations, (2) chest peak resultant accelerations, (3) femur peak loads, (4) head peak forward displacements, and (5) knee peak forward displacements. An analysis of the absolute deviations of the data points from the overall means demonstrated that the dummy performance variations were generally within an acceptable level. In addition, performance comparison overlay time-history graphs are presented for direct comparisons.
