摘　　要：汽车安全领域的智能化和数字化发展都急需能代表真实人体特征的生物力学计算模型。本文以最新中国成年人人体尺寸标准为依据,开发具有自主知识产权的50^(th)百分位中国男性体征汽车乘员生物力学模型(TUST IBMs M50-O)。通过重构3组正面钝性冲击、5组侧面钝性冲击和3组整人滑车尸体及志愿者试验,模拟C-NCAP可变形移动壁障侧面碰撞试验,多角度、全方位验证所开发模型的有效性及应用价值。结果表明:11组重构试验数据均在相应的尸体及志愿者试验通道内,平均差异在10%左右,验证了模型的有效性。TUST IBMs M50-O与WorldSID 50^(th)假人模型在侧面碰撞中的运动趋势相同,但TUST IBMs M50-O模型上肢对胸部的挤压,使得胸椎T4和T12质心合成加速度峰值达到43.5g和47.3g,高于WorldSID 50th模型峰值38.5g和41.2g。同时,TUST IBMs M50-O模型也从应力应变角度评估人体组织层面的损伤风险。综上,TUST IBMs M50-O模型展现了类似真实人体的高生物逼真度,可用于组织层面的损伤机理研究,也可为智能汽车安全防护装置及智能高端装备领域产品研发、汽车虚拟测评提供可靠的计算工具和技术支撑。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 50^(th)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 50^(th)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 50^(th)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.
