摘  要:为探究特种车辆内乘员在垂直方向安全性评价的有效指标,进行了两种不同强度的爆炸试验,针对小腿部位按照3种不同伤害评价指标,即Yoganandan评价指标、Hirsch评价指标和胫骨指数(TI),分别从小腿轴向力、加速度、综合小腿轴向力和力矩3方面进行乘员小腿伤害风险分析,结果表明:在乘员受到轻微爆炸冲击和剧烈爆炸冲击两种工况下,这3种评价指标结果较为一致,均可有效评价人员小腿安全性。此外,在Hirsch评价指标中,采用地板加速度而非足底加速度将得到更为准确的结果。

Two explosion tests under different intensities of blast loading were carried out to research the valid index to evaluate the vertical safety of the passengers in some special vehicles, and the injury risk of the occupant tibia in aspects of the tibia axial compressive force, the acceleration and the combination of force and moment, were analyzed to evaluate the injury probability of the tibia, which were based on three different injurycriteria (Yoganandan Criterion, Hirsch Criterion, and tibia index (TI) ). The results show that the accord anceamong the three criteria, each of which is suitable for the evaluation of the occupant tibia’s injury risk under slight and serious blast loads. Moreover, the floor acceleration other than the foot acceleration can lead to more accurate result when using Hirsch Criterion.
