WorldSID 50th假人与ES-2假人的性能对比分析

摘要

为深入了解全球侧碰50百分位男性(WorldSlD 50th)假人在整车侧面碰撞中的响应,针对整车侧面碰撞工况中使用的WorldSID 50th假人和ES-2假人结构的差异,在摆锤冲击标定工况的基础上进行了扩展,采用不同的冲击速度对WorldSID 50th假人和ES-2假人的胸部、腹部、髋部的评价指标进行了规律性分析,并从伤害得分的难易程度上分析了假人各个部位的承受能力,直观地显示出假人不同部位的响应特性.结果表明:在同样冲击条件下,WorldSID 50th假人的胸部承受能力略好于ES-2假人,但腹部和髋部与ES-2相比具有较好的承受能力.此研究中针对两个假人摆锤冲击工况的研究和解析,为进一步研究WorldSID 50th假人在整车侧面碰撞中的响应提供了基础,具有一定的指导意义.%The difference between WorldSID 50th dummy and ES-2 dummy was studied deeply to clarify the response of WorldSID 50th dummy in vehicle side impact load case.By extending pendulum impact calibration method,the evaluation index regularity and the response character of dummy were investigated of the two dummy's chest,abdomen and pelvis in different impact velocity so that the bearing capability of different part for different dummy was clarified.The result shows that the bearing capability of WorldSID 50th dummy's chest is slightly better than that of ES-2 dummy,but the abdomen and pelvis of WorldSID 50th dummy has much better bearing capability than those of ES-2 dummy in same load case,which lay the good foundation for clarifying WorldSID 50th dummy response completely in vehicle side impact load case.
