This study evaluated the biofidelity of the WorldSID and the ES-2re under whole-body side impact conditions with and without a side airbag using the biomechanical cadaveric response data generated from 4.3m/s whole-body side impact tests. Impact forces, spinal kinematics, and chest deflections were considered in the biofidelity evaluation. Average responses and response corridors of PMHS were created using a time-alignment technique to reduce variability of the PMHS responses while maintaining the sum of the time shifts to be zero for each response. Biofidelity of the two dummies was compared using a correlation and analysis (CORA) method. The WorldSID demonstrated better biofidelity than the ES-2re in terms of CORA ratings in the conditions with airbag (0.53 vs. 0.46) and without an airbag (0.57 vs. 0.49). Lastly, the kinematic analysis of the two dummies indicated an overly compliant shoulder response of the WorldSID and excessive forward rotation of the ES-2re relative to the PMHS.
本研究利用4.3米/秒全身侧面碰撞试验产生的生物力学尸体响应数据，评估了WorldSID和ES-2re在有和没有侧面安全气囊的全身侧面碰撞条件下的生物逼真度。在生物逼真度评估中考虑了撞击力、脊柱运动学和胸部变形。使用时间对齐技术创建了PMHS的平均响应和响应走廊，以减少PMHS响应的变异性，同时保持每个响应的时间偏移总和为零。使用相关性和分析（CORA）方法比较了两个假人的生物逼真度。在有安全气囊（0.53对0.46）和没有安全气囊（0.57对0.49）的条件下，就CORA评级而言，WorldSID的生物逼真度优于ES-2re。最后，对两个假人的运动学分析表明，WorldSID的肩部响应过于柔顺，而ES-2re相对于PMHS有过度的向前旋转。
