Abstract

The optical thorax deflection sensing system (for the Hybrid III dummy), introduced at the 13th ESV Conference, was studied for the feasibility in Advanced Anthropomorphic Test Device (AATD) dummy which the SAE Task group on Frontal Impact Dummy Enhancement has been developing as a next-generation dummy. The optical thorax deflection sensing system measures the displacement of target points based on trigonometry by sensing the light of LEDs attached to the target points within a thorax with cameras fixed to the spine. The camera layout used before could not be employed because the lateral distance between the target points in the AATD dummy is greater. It was found that the system can be made feasible in the AATD dummy by rearranging the combination of the target points and cameras and optimizing the relative position between cameras and mirrors.
