Abstract:

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.
