Design and Development of an Advanced ATD Thorax System for Frontal CrashEnvironments. Final Report. Volume 3. User Guide for Chest Deflection Measurement System. Trauma Assessment Device Development Program

摘要

The report documents a research and development effort to design and test a newthorax assembly that will improve performance with regard to restraint-system interaction and injury-sensing capability for the chest and abdomen. The new features include a ribcage with more humanlike geometry, an articulated thoracic spine, shoulders with load-bearing clavicles connected to the sternum and enhanced front/back range of motion, a biofidelic frangible abdomen, and a chest deflection measurement system capable of monitoring three-dimensional displacements of the ribcage at the sternum and at the left and right regions of the lower ribcage. Volume 3 describes the chest deflection instrumentation system developed in the project and provides a user's guide for a subprogram DEFLECT that computes three-dimensional displacements at four regions of the thorax.
