摘要/Abstract

摘要： 使用ABAQUS有限元分析软件,按照GB/T 24500-2009规定建立了成人头部冲击器撞击碳纤层合板模型,探讨了9种铺层方式下,头部伤害指标HIC值与最大侵入量、撞击持续时间和冲击能量吸收之间的关系,并比较了层合板不同铺层角度对行人头部损伤的影响。结果表明,HIC值大小基本与最大侵入量、撞击持续时间和冲击能量吸收有一定的反比关系;铺设三种角度的层合板最有利于行人头部保护;45°方向铺层对降低HIC值和减小最大侵入量贡献最大。

关键词: ABAQUS, 头型冲击器, 碳纤层合板, 铺层角度, HIC值, 最大侵入量

Abstract: In this paper, the FE model of collision between head impactor and CFRP laminate was established in the ABAQUS software according to the GB/T 24500-2009 standard. Nine laminate layups were designed to analyze the effects layup degree types and different layup degrees had on both HIC value and maximum penetration. The HIC value relationships with maximum penetration, impact duration and impact energy absorption were also evaluated. It was shown that HIC value had certain inverse relationships with maximum penetration, impact duration and impact energy absorption; laminate with three-degree type was the best for head protection; forty-five degree contributed the most in decreasing HIC value and maximum penetration.

Key words: ABAQUS, head impactor, CFRP laminate, layup degree, HIC value, maximum penetration
