1302 TRLおよびフレキシブル脚部インパクタを用いた実卓衝撃試験における障害値評価特性(OS5-1:交通・物流機械の安全技術,OS5:安全・安心・防災・環境負荷低減,オーガナイズド・セッション(OS),第18回交通・物流部門大会(TRANSLOG2009))

Abstract

This study investigated the equal possibility of injury risk estimation using both the TRL and the flexible legform impactors. Nineteen locations of eight different Japanese vehicles (including sedan, sport utility vehicle (SUV), height wagon, and I box cars) were impacted by the TRL and the flexible legform impactors, respectively. In this study, the fitting ratio was defined as the number in an area where the measured criteria either fulfilled both requirements or exceeded both requirements of the TRL and the flexible legform impactors divided by the number in the all test cases (n=19). The fitting ratio for the tibia fracture risk assessment was 63%. In contrast, the fitting ratios for the ACL, PCL and MCL injury risk assessments were 84%, 79% and 84%, respectively. Therefore, the knee ligament injury risk assessment was at a higher level as compared to the tibia fracture risk assessment between the TRL and the flexible legform impactors.
