人体肌肉骨骼系统的生物材料在接触爆炸的冲击波冲击下的破坏过程的有限元模拟模型已得到证实，可用于预测人体下肢损伤的性质和程度，包括设计特殊防爆鞋。分析了描述人体下肢生物组织物理力学特性及其在局部冲击波作用下行为的科学数据。作为人体下肢数学模型的一部分，对每种生物材料的机械性能进行了选择。对人体下肢的原始有限元模型进行了论证，并调整了其主要组成解剖结构之间的相互作用。利用机械和冲击波效应实验结果获得的数据对开发的计算模型进行了验证。创建了一个处理所获数据的专门程序，其中采用了一种算法来处理所获得的压力和加速度指数随时间变化的图形图像，以获得公差曲线。通过所开发的下肢模型的防护组合，进行了一系列模拟接触爆炸的数值计算。根据计算结果，获得了压力和加速度的公差曲线，创建了冲击波作用下人体下肢解剖结构行为的动画，并获得了压力场在其中传播的可视化效果。今后，所介绍的进行“虚拟”测试的方法可用于解决爆炸物处理下肢防御设备开发阶段测试的一些应用问题。总之，计算机建模技术的应用将有助于减少生产新防护产品样品的时间和成本，从而提高国家的防御能力。
