摘要/Abstract

摘要： 基于中国人体头部尺寸参数，采用非均一线性缩放方法对混合Ⅲ型(Hybrid Ⅲ)假人头部模型进行缩放获得了符合中国50百分位人体尺寸的假人头部模型。利用该模型建立头部标定试验仿真模型，研究了假人头部模型质心设计参数对中国假人头部模型在标定试验中动态响应的影响，通过与Hybrid Ⅲ假人头部标定试验响应的对比，探讨了基于中国人体尺寸的假人头部模型质心参数设计依据。结果表明，缩放所得中国假人头部模型合成加速度峰值较Hybrid Ⅲ假人头部模型大8.6%；质心参数对中国假人头部模型合成加速度峰值的影响比Hybrid Ⅲ假人头部模型明显；当前Hybrid Ⅲ假人头部模型质心偏差要求不适用于中国假人头部模型质心参数设计，中国假人头部模型的生产应制定更严格的质心偏差要求。

Abstract: Based on the Chinese anthropometric dimensions,the finite element(FE) models of Chinese 50th percentile human body sizes dummy heads were developed by scaling the Hybrid Ⅲ dummy heads using non-uniform linearity scaling method.The head calibration was simulated to study the influences of centroid parameters on the dynamic responses.The design basis was discussed by comparing the results of Chinese dummy heads and Hybrid Ⅲ heads. The results show that the peak accelerations of Chinese dummy heads are as 8.6% larger than that of Hybrid Ⅲ dummy heads. The effects of the centroid parameters on the peak accelerations for Chinese dummy heads are larger than that of Hybrid Ⅲ dummy heads. The current requirements of the center of gravity(CG) of Hybrid Ⅲ dummy heads are not applicable to the designs of Chinese dummy heads, and more rigorous requirements should be needed for the manufacture of Chinese dummy heads.

Key words: dummy head model, scale, centroid parameters, head calibration, peak acceleration
