Abstract
Anthropomorphic Test Devices (ATD) are the backbone of any crash research lab, their performance during the crash tests being of paramount importance to assess the vehicle performance. The Hybrid III 50th percentile dummy (H350) is one of the most recognized and accepted ATD for research in this field.
However several unusual results of the dummy injuries in a vehicle crash test indicate some discrepancies exists in the dummy design. This prompted researchers to investigate such things and this paper is based on a project conducted to study the chest deflection of the hybrid 350 dummy.
The project deals with assessing the dummy's chest deflection response sensitivity to load location as well as ambient operating conditions. The scope involved testing of the dummy chest by loading it quasi-statically on a UTM as well as dynamically impacting it on the dummy calibration rig. The chest deflection or thorax displacement data and loading data was gathered and analyzed further.
The paper explains the reason behind undertaking such a project and methodology followed for the execution, the rationalized data analysis and conclusion thereof.
The sensitivity or response of the dummy chest to the parameters selected was validated though the tests. The response is more pronounced in the dynamic tests.
