交通事故における傷害低減のための人体FEモデルの構築

摘要

In late years, the number of fatalities and injuries in traffic accidents has decreased by the improvement of crash safety technologies. However, around six thousand people have still been killed and more than one million people have been injured every year in Japan. While this decreasing trend can be seen in advanced countries as well, the fatalities and injuries are predicted to continue to increase dramatically in developing countries due to rapid growth of motorization. In order to reduce those victims of traffic accidents, additional improvement of automotive safety is still required. The Japan Automotive Manufacturers Association (JAMA) performs various kinds of activities for the improvement of automotive safety. JAMA has been developing a finite element human model for crash safety as one of those activities since 2004. This report presents the status of the development of the JAMA finite element human model.%近年衝突安全性能の向上により，交通事故死者負傷者rn数は減少傾向にはあるものの，日本国内では依然6 000rn人弱の死者と100万人以上の負傷者が毎年発生しているrn（図1）．また海外においても，先進国での減少傾向はあrnるものの，進展国ではモータリゼーションの急激な発展rnにより死者負傷者の増加が継続するとみられている．そrnれらの交通事故による犠牲者をさらに減少させるためにrnは，車両においてもさらなる安全対策が必要とされる．
