The demand for blastworthy structures increases due to a large number of casualties in the armored vehicle undergoing improvised explosive device (IED) and landmine attacks. In this research, the numerical studies on the countermeasure analysis to reduce injury biomechanics risk were conducted. The available experiment data of occupant survivability test on a medium size tank was used to validate the numerical model. The subsystem evaluation in this study included the finite element modeling of military personnel, seat system, surrounding interior system, seatbelt, and restraint system with four running conditions. The military personnel inside the armored vehicle was modeled by using Hybrid III 50^th percentile anthropomorphic test device (ATD) and its biomechanical response was monitored on the head, neck, thorax, spine, femur, and tibia. The load case for this study referred to NATO STANAG 4569 level 3b with 8 kg TNT explosive load underbelly. The injury assessment reference values (IARV) for the regulation used in this study were based on AEP-55 volume 2. Based on this study, the critical injuries identified on the head injury, neck compression, and tibia axial load. The solid frame as part of seat structure appeared to contribute to an excessive kinematic on the lower extremities. The vehicle acceleration resulted from the load blast was directly transmitted to the lower extremities, resulting in unintended kinematic and interaction on the passenger body. The proposed solutions were to introduce a flexible mounting for the seat system and as well increasing the height of the footrest to avoid direct transmission of vehicle acceleration. The modified countermeasure design reduced significantly head, neck, and tibia injury criteria more than 90 % from the baseline design (existing design). The new anti-mine seat design successfully passed all the standard regulation thresholds of injury criteria.

由于遭受简易爆炸装置（IED）和地雷袭击的装甲车中有大量人员伤亡，对具有爆炸性结构的需求增加。在这项研究中，进行了减少伤害生物力学风险的对策分析的数值研究。利用中型水箱上乘员生存能力测试的可用实验数据来验证数值模型。本研究中的子系统评估包括具有四个运行条件的军事人员，座椅系统，周围内部系统，安全带和约束系统的有限元建模。装甲车内的军事人员是使用Hybrid III 50 ^th建模的百分位拟人化测试设备（ATD）及其生物力学响应在头部，颈部，胸部，脊柱，股骨和胫骨上进行监测。本研究的载荷案例是指北约STANAG 4569 3b级，其腹部有8 kg TNT爆炸载荷。本研究中使用的法规的伤害评估参考值（IARV）基于AEP-55第2卷。基于该研究，确定了在颅脑损伤，颈部受压和胫骨轴向负荷方面的严重伤害。作为座椅结构一部分的坚固框架似乎导致下肢运动过度。负载爆炸产生的车辆加速度直接传递到下肢，导致乘客身上意外的运动学和相互作用。提出的解决方案是为座椅系统引入灵活的安装方式，并增加脚凳的高度，以避免车辆加速度的直接传递。修改后的对策设计与基线设计（现有设计）相比，显着减少了90％以上的头部，颈部和胫骨损伤标准。新的防雷座椅设计成功通过了伤害标准的所有标准规定阈值。
