摘要: 头盖骨对于维持生命安全至关重要。作为一种多孔夹芯结构,头盖骨由密质骨面板和松质骨芯子构成。本文通过头盖骨截面与冲击物相互作用,并基于能量守恒定律分析了人头盖骨能量吸收随着冲击速度的变化规律,给出了头盖骨在不同冲击速度下的破坏形貌图。通过头盖骨截面的失效面积,反映出结构的吸能特性。

关键词: 多孔结构, 密质骨, 松质骨, 冲击速度, 能量吸收

Abstract: Skull bone plays a significantly important role in sustaining life safety. As a cellular sandwich structure, skull bone is composed of compact bone (panel) and cancellous bone (core). Through the interaction between the skull section and impactor, the variation tendency of energy absorption of human skull bone with impact velocity has been analyzed based on energy conservation law in this paper. The failure topography of the skull bone under different impact velocities has been provided, and the structural energy absorption characteristics also have been reflected according to the failure area of the skull section.

Key words: cellular structure, compact bone, cancellous bone, impact velocity, energy absorption
