Validation of Age-specific Human FE Models against Side Impact

年齢別人体FE モデルの側面衝撃に対する検証

Corresponding to the increasing need for the protection of elderly people from traffic accidents, the authors have been developing age-specific human FE models capable of predicting body kinematics and skeletal injuries for younger adult (35y.o.) and the elderly (75y.o.). The models have been developed and validated part by part referring to the literature and then integrated into whole bodies. Validation had been conducted in order of single bones, components and whole body. Whole body kinematics in frontal impact had been validated against the PMHS frontal belt restrained sled tests series, resulting in good biofidelity scores. In this study, the models were validated for lateral impact. The models were validated against several impact tests of body regions from ISO-TR9790 and against recently published full scale lateral sled tests for whole body kinematics. In most cases, the results showed good biofidelity of the models. Capability of the rib fracture prediction was also discussed.近年対応の必要性が高まっている,交通事故に対する高齢者保護のために,著者らは成人および高齢者の挙動および傷害評価が可能な人体FEモデルの開発を行ってきた.これまでに骨の単体,部分衝撃,正面衝突時の全身挙動の予測精度検証を行ってきたが,今回は側面からの衝撃に対する応答予測の検証結果を発表する.
