J-MLIT Research onto a Pedestrian Lower Extremity Protection - Evaluation Tests for Pedestrian Legform Impactors

As for a Global Technical Regulation (GTR) legform impactor, which is discussed at the United Nations ECE/WP29/GRSP, a flexible pedestrian legform impactor (Flex-PLI) and a rigid legform impactor (TRL-LFI) are proposed. However, as for the Flex-PLI, evaluation test for its repeatability and reproducibility has not been confirmed. Besides, its advantage over the TRL-LFI must be demonstrated in full-scale vehicle tests. In this research, several kinds of loading tests were conducted on the Flex-PLI, and its favorable repeatability and reproducibility was confirmed. Besides, vehicle tests were performed using the Flex-PLI and the TRL-LFI, and the Flex-PLI demonstrated its higher biofidelity and load measurability in full-scale vehicle tests.
