Abstract:

The biomechanical human body model with detailed anatomical characteristics is urgently needed computational tool for the intelligent and digital development in the field of automotive safety. In this study, based on the latest Chinese adult body size standards, a biomechanical model of the 50th percentile Chinese male anthropometry car passenger (TUST IBMs M50-O) is developed with independent intellectual property rights. By reconstructing 3 sets of frontal blunt impacts, 5 sets of side blunt impacts, and 3 sets of sled cadaver or volunteer tests, the C-NCAP deformable moving barrier side impact test is simulated to verify the effectiveness and application value of the developed model from multiple angles and all directions. The results show that all the 11 sets of reconstructed experimental data are within the corresponding cadaveric and volunteer corridors, with an average difference of approximately 10%, verifying the effectiveness of the model. The TUST IBMs M50-O model and WorldSID 50th model exhibit the same kinematic responses in the side impact simulation. However, due to the compression from the upper extremity and elbow joint of the TUST IBMs M50-O model, the peak resultant accelerations of T4 and T12 thoracic spine reach 43.5g and 47.3g, higher than the values of 38.5g and 41.2g of the WorldSID 50th model. The TUST IBMs M50-O model is also used to analyze the human tissue level injury risks based on stress and strain. In conclusion, the TUST IBMs M50-O model exhibits high biofedility and can be used to investigate the impact of injury mechanisms and virtual testing. As a reliable computational tool, this model can offer technological support to the research and development of safety protection devices in intelligent vehicles and intelligent high-end equipment.
