The aim of this study was to assess the ability of lower limb surrogates to predict injury due to floor/foot plate impact in military vehicles during anti-vehicular land mine explosions. Testing was conducted using two loading conditions simulated to represent those conditions created in the field. The lower condition was represented by a 24-kg mass impactor with a velocity of 4.7 m/s. The higher loading condition was represented by a 37-kg mass impactor with a velocity of 8.3 m/s. Two biomechanical surrogates were evaluated using the loading conditions: 50th percentile Hybrid III foot/ankle and Test Device for Human Occupant Restraint THOR-Lx. Comparisons of the force-time response were made to established corridors. Results show a better correlation to the corridors with the THOR-Lx; however, future improvements to the THOR-Lx are recommended.
本研究的目的是评估下肢替代物预测反车辆地雷爆炸时军车地板/脚踏板撞击导致损伤的能力。测试使用了两种模拟加载条件,以代表现场产生的条件。较低加载条件由一个质量为24千克、速度为4.7米/秒的撞击器表示。较高加载条件由一个质量为37千克、速度为8.3米/秒的撞击器表示。使用这些加载条件对两种生物力学替代物进行了评估:第50百分位的Hybrid III足/踝和人体乘员约束试验装置THOR-Lx。将力-时间响应与既定的通道进行了比较。结果表明,THOR-Lx与通道的相关性更好;然而,建议对THOR-Lx进行进一步改进。
