基于经验证的Hybrid III有限元模型,进行假人胸部水平面内斜角度碰撞的仿真,对比了其在不同角度(30°,45°和60°)、不同速度的撞击下的动力学响应和变形特性,分析了Hybrid III胸部斜向受载的生物逼真度。结果表明,Hybrid III胸部斜向动力学响应不符合人体尸体响应要求,斜向载荷作用下假人胸部内置传感器的输出会显著低估了胸部可能遭受的伤害风险,容易得出错误的胸部损伤评估结论。

Based on verified Hybrid-III finite element model, a simulation of the oblique impact on dummy thorax in horizontal plane is conducted to compare its dynamics response and deformation characteristics with differ-ent impact angles (30°,45° and 60°) and impact speeds, and analyze the biofidelity of Hybrid-III thorax under ob-lique crash. The results show that the dynamics response of Hybrid-III thorax to oblique impact is not in accordance with the biomechanical responses of human cadaver and the output of the built-in sensor of dummy thorax under ob-lique loading may obviously underestimate the injury risk of thorax, which is then prone to lead to erroneous conclu-sion on thorax injury assessment.
