本文对新鲜人颅骨结构的静力和动力特性分别进行了有限元分析和测试。计算和测试结果表现出良好的一致性。文中给出了应力分布规律,提出了重点防护部位,说明了人颅骨结构属于小阻尼结构,在动力分析时可以抽象成弹性阻尼薄壳结构。
In this paper, the static and dynamic characteristics of fresh human skull structure were analyzed by finite element method and tested. Calculations and test results showed good agreement. The paper presents the law of stress distribution and puts forward the key protective parts. It shows that the human skull structure belongs to the small damping structure, and the elastic damping thin shell structure can be abstracted in the dynamic analysis.
