Statistical Analysis of the MVMA (Motor Vehicle Manufacturers Association) Side Impact Test Data

摘要

Results of a statistical analysis of 40 full-scale side impact tests conducted by MVMA to evaluate NHTSA and European test procedures are presented. The first sixteen tests were conducted with the NHTSA side impact dummy following the NHTSA-proposed test procedures. The remaining 24 tests were conducted with the European side impact dummy, and included both the NHTSA and European test procedures, as well as a combination of the two. The objectives of the tests were to determine the ability of the test procedures and dummies to discriminate the effects of deliberate changes in the test vehicle, and to evaluate the compatibility of the NHTSA and European test procedures. Among the injury measures, the Thoracic Trauma Index (TTI) in particular, and deceleration measures in general, had smaller variances and discriminated effects with greater statistical significance. Variability was substantially greater for the Viscous Criterion and deflection measures.
