Offset Frontal Crash Research in Japan

This paper is a compilation of the present state of research in Japan relating to offset frontal crashes using a deformable barrier. It contains an analysis of actual accidents in Japan, accident reproducibility tests implemented using vehicles as examples of representative accidents and a consolidation of the results of studies of reproductive techniques reproduced using a deformable barrier based on the accident reproducibility test results. In the deformable barrier tests, in the case of changes in the offset ratio, barrier face form, barrier face rigidity, crash velocity and the like, the degree of change of vehicle behavior, dummy behavior, vehicle deformation and the dummy injury values have been compared with the results study of accident reproducibility tests. From these results, basic data was obtained relating to test methods for offset deformable barrier collisions.
