Abstract

THOR-AV 5F, a modified THOR-5F dummy, was designed to represent both upright and reclined occupants in vehicle crashworthiness studies. The dummy was evaluated in four test conditions: a) 25° seatback, 15 km/h, b) 25° seatback, 32 km/h, c) 45° seatback, 15 km/h, d) 45° seatback, 32 km/h. The dummy's biomechanical responses were compared against those of postmortem human subjects (PMHS) tested in the same test conditions. The latest National Highway Traffic Safety Administration (NHTSA) BioRank method was used to provide a biofidelity ranking score (BRS) for each data channel in the tests to assess the dummy's biofidelity objectively. The evaluation was categorized into two groups: restraint system and dummy. In the four test conditions, the restraint system showed good biofidelity with BRS scores of 1.49, 1.47, 1.15, and 1.79, respectively. The THOR-AV 5F demonstrated excellent biofidelity in three test conditions: 25° seatback, 15 km/h (BRS = 0.76); 25° seatback, 32 km/h (BRS = 0.89); and 45° seatback, 32 km/h (BRS = 0.93). In the fourth test condition, 45° seatback, 15 km/h, the dummy demonstrated good biofidelity with a BRS score of 1.06. The dummy demonstrated good durability. No damage was identified with a full inspection conducted after the tests.

使用半刚性座椅进行雪橇测试条件下的 THOR-AV 5F 生物保真度研究。
THOR-AV 5F 是一种改进型 THOR-5F 假人,设计用于在车辆耐撞性研究中代表直立和倾斜的乘员。该假人在四种测试条件下进行了评估:a) 25°椅背,15 km/h;b) 25°椅背,32 km/h;c) 45°椅背,15 km/h;d) 45°椅背,32 km/h。假人的生物力学反应与在相同测试条件下进行测试的死后人体受试者(PMHS)的生物力学反应进行了比较。采用美国国家公路交通安全管理局(NHTSA)最新的 BioRank 方法为测试中的每个数据通道提供生物保真度排名得分(BRS),以客观评估假人的生物保真度。评估分为两组:约束系统和假人。在四种测试条件下,约束系统显示出良好的生物逼真性,BRS 分数分别为 1.49、1.47、1.15 和 1.79。在三种测试条件下,THOR-AV 5F 的生物保真度极佳:25°椅背,15 km/h(BRS = 0.76);25°椅背,32 km/h(BRS = 0.89);45°椅背,32 km/h(BRS = 0.93)。在第四种测试条件(45°椅背,15 公里/小时)中,假人表现出良好的生物逼真性,BRS 得分为 1.06。假人表现出良好的耐用性。测试后进行的全面检查未发现任何损坏。
