冲击力作用下人体动态响应变化

HUMAN DYNAMIC RESPONSE UNDER DIFFERENT IMPACT

为探讨人体在不同冲击力作用下的动态响应过程及可能造成的损伤,开展了人体在冲击力作用下仿真模型的研究。在冲击塔上进行了5人15次的真人冲击试验,获得人体在冲击力作用下的头部和胸部输出响应变化值。在自编写的人体力学参数数据库中获得相应的人体力学参数,基于ADAMS／Lifemod软件建立相应的人体动力学仿真模型。所建立的模型与真实的试验结果具有较好的一致性,说明所建立的人体在冲击力作用下的仿真模型能用于冲击力作用下人体安全性的评估。

In order to study the response of human body and the probable injury under different impact, the human dynamic model under impact is created. Five men （15 times） are experienced various impacts on the impact tower. The dynamic responses of different segments of human body such as the head and chest are analyzed. And by using the parameters from human kinetic parameters database, the human dynamic model is created in ADAMS/Lifemod software. The results of model under different impact are compared to those got from truly results of human experiencing the same impact. The comparison proves that the model has high reliability. The human impact dynamic model can be used in evaluating human safety under different impact.
