摘要

近年来,人们对慢性创伤性脑病(CTE)和相关脑震荡的兴趣日益浓厚,这些脑震荡发生在专业和业余水平的体育运动中。随后,人们对开发新型运动头盔产生了兴趣,这种头盔既能吸收能量,又能检测和减少脑震荡。为了测试这些头盔,必须使用合适的头部形状,既适合头盔,又能表现出人类头部的动态特性。虽然在制造包含汽车碰撞测试仪器的仿生头方面已经付出了很多努力,但这些头的成本可能高达1万美元。这个项目的目标是创造一个几百美元的头部形式,具有适当的动态特性,用于测试头盔的线性和角加速度。该项目的具体目标是创造一个具有以下特征的头部形状:1)外部尺寸和形状将适当适合曲棍球头盔;2)成人头部的体重代表;坚固到足以承受一千次冲击试验。介绍了头型的制作及设计目标的验证。

Development of a Low-Cost Mechanical Model of a Human Head
In recent years, interest has developed in Chronic Traumatic Encephalopathy (CTE) and the related concussions that occur in sports at both professional and amateur levels. Subsequently there is interest in developing new types of athletic helmets to both absorb energy to detect and reduce concussions. To test these helmets, an appropriate head form must be used that will fit the helmet and also exhibit the dynamic properties of the human head. While much effort has gone into creating biofidelic heads containing instrumentation for automotive crash testing, these heads can cost upwards of $10,000. The goal of this project is to create a head form for a few hundred dollars with the appropriate dynamic properties for testing linear and angular accelerations of a helmet. The specific goals of this project are to create a head form with the following characteristics: 1) External size and shape that will properly fit a hockey helmet; 2) Weight representative of an adult head; 3) Robust enough to withstand a thousand impact tests. The manufacture of the head form and the verification that the design goals are described.
