Comparative Study on the Biofidelity of Test Dummies Under Multi-Angle Far-Side Impact Conditions

中文摘要英文摘要

探究WorldSID与THOR两款假人在不同角度侧面远端碰撞工况下的生物力学响应差异,评估其工程适用性与生物逼真度.基于有限元仿真方法,建立涵盖0°(正面)至90°(纯侧面)的多种斜置远端碰撞工况,以THUMS高精度人体模型为基准,对比分析两款假人头部及胸部(T1,T8,T12)的加速度响应,并采用皮尔逊相关系数进行定量逼真度评价.结果表明,假人的适用性呈现出显著的碰撞角度与身体部位依赖性,THOR假人在正面碰撞(0°)及小角度斜向远端碰撞(0°~45°)工况下,其头部与下胸部(T8、T12)的动力学响应与THUMS人体模型具有更高的相关性;而WorldSID假人在侧面远端碰撞工况(30°~90°)中,头部及上胸部(T1)展现出更高的生物逼真度,且在大角度碰撞条件(60°~90°)下,其下胸部响应同样优于THOR假人.为车辆安全虚拟测评体系中针对不同侧面远端碰撞场景选择适宜的假人提供了关键的数据支撑与理论依据.

This study investigates the biomechanical response differences between the WorldSID and THOR dummies under far-side impact conditions at various angles and evaluates their engineering applicability and biofidelity.Finite element simulations were conducted to model multiple oblique far-side impact scenarios,ranging from 0°(frontal)to 90°(pure lateral).The high-fidelity THUMS human model served as the benchmark for comparing the acceleration responses of the head and chest(T1,T8,T12)of both dummies,with biofidelity quantitatively assessed using the Pearson correlation coefficient.The results demonstrate that dummy applicability strongly depends on impact angle and body region.Specifically,the THOR dummy shows higher correlation with THUMS in head and lower chest(T8,T12)responses under frontal(0°)and small-angle oblique(0°~45°)impacts.In contrast,the WorldSID dummy exhibits superior biofidelity in the head and upper chest(T1)under far-side impact conditions(30°~90°),along with better lower chest responses at large impact angles(60°~90°).This study provides critical data and theoretical support for selecting appropriate dummy models in virtual vehicle safety evaluations across different collision scenarios.
