Statistical Analysis of the JAMA (Japanese Automobile Manufacturers Association) Side Impact Test Data

摘要

The report presents the results of an analysis of 16 full-scale side impact crash tests that were conducted by the Japanese Automobile Manufacturers Association. The objective is to examine the influence of the major factors distinguishing the proposed U.S. and European passenger car side impact test procedures on the resulting injury measures. The factors addressed are the dummy, the moving deformable barrier, and the impact angle of the barrier. When the results from the Japanese tests were compared with similar tests conducted by the U.S. manufacturers the differences were inconsistent. Some combinations of dummy and test procedure indicated that the injury measures were much higher in the Japanese compact car as compared to the full size U.S. car, while other combinations of dummy and test procedure showed similar injury numbers for the two cars. These results underscore the importance of the differences in the proposed U.S. and European side impact tests and the obstacles to international harmonization.
