Abstract
Pedestrian protection analyzing technologies have been developed. They are based on the impactor test methods, for head, lower leg, and upper leg which are proposed by EEVC WG17. The analyzing technologies are applied to the study on from the initial development stage to the detailed engineering stage. We introduce the features and accuracy of our analyzing technologies using Microsoft Excel, MADYMO and PAM-CRASH. Furthermore, these technologies were applied to a prototype car development to study the efficient structure. In this paper, a development of a fender for head protection and a bumper structure with high leg protection performance is reported. The developed bumper was tested and evaluated on an actual vehicle and was proven to have high leg protection performance. The leg protection analyzing technology could estimate the leg injury of a actual vehicle test within 10% prediction error.
