本文介绍了如何利用所建模型确定人体对弹射加速度的耐力。人体耐力以椎骨损伤概率作指标,并将系统最大超调量与椎骨的破坏强度相结合以确定人体的耐力限度。人体响应为18.5G、21.7G、25.7G时,椎骨破坏概率为5%、50%、95%。根据人体模型的动力特性表明,人体最大超调为50%,因而得到人体耐受弹射加速度值分别为12G、14G、17G以及相应的ΔV值。文中还分析了所建模型与DRI模型的关系,二者是不同途径得到的同一结果。
This article describes how to use the model to determine the body’s resistance to ejection acceleration. Human endurance to vertebral injury probability as an indicator, and the system maximum overshoot combined with the destruction of vertebral strength to determine the body’s endurance limits. Human body response to 18.5G, 21.7G, 25.7G, vertebral destruction probability of 5%, 50%, 95%. According to the dynamic characteristics of human body model shows that the human body maximum overshoot of 50%, resulting in human body resistance ejection elastic values were 12G, 14G, 17G and the corresponding ΔV value. The article also analyzes the relationship between the built model and the DRI model, the two are the same result obtained by different ways.
