Modeling and Verification for Chest and Abdomen of Chinese Human Digital Model for Traffic Safety

doi:10.3901/JME.2025.18.299

Abstract

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
