摘要: 作为中国汽车工程研究院先进中国体征人体数字模型AC-HUMs工作的一部分,旨在利用中国50百分位体征几何数据建立具有详细解剖学结构的人体胸腹有限元模型,对关键骨骼数据利用7大片区数据校核,并对标文献尸体试验数据对该模型进行多种载荷工况下的生物逼真度验证。建立的人体胸腹部模型以中国人体数据为依据,结果表明该模型能够代表中国50百分位男性的生物力学特征,所建人体胸腹部有限元模型具有较高的生物逼真度,且在常规冲击载荷下模拟计算表现出了高稳定性,可为中国交通参与者胸腹部损伤特征研究提供有效工具。

Abstract: As part of the work of the Advanced Chinese Anthropometry-based human digital models (AC-HUMs) project at China Automotive Engineering Research Institute, the aim is to use the geometric data of the 50th percentile of Chinese anthropometry to establish a finite element model of the human chest and abdomen with detailed anatomical structures. The key bone data is verified using the data from seven major regions, and the biofidelity of this model under various load conditions is validated by benchmarking it against the cadaver test data in the literature. The established human chest and abdomen model is based on Chinese human body data. The results show that this model can represent the biomechanical characteristics of Chinese males at the 50th percentile. The established finite element model of the human chest and abdomen has a high level of biofidelity and demonstrates high stability in simulation calculations under conventional impact loads. It can provide an effective tool for studying the characteristics of chest and abdomen injuries among Chinese traffic participants.

Key words: Chinese human body characteristics, thoracoabdominal model, finite element modeling, model verification
