Abstract

The purpose of this paper is to study the effect of body stiffness on the accuracy of reconstruction of pre-impact speed in one-dimensional collisions, and to enable more accurate reconstruction case by case than previous studies. This paper shows, by comparing body stiffness data of several types of automobiles, that the appropriate method depends on their relations. In addition, this knowledge is validated based on actual collision tests. The body stiffness data used in this study is mainly based on the data obtained in the Japan New Car Assessment Program (JNCAP).
