Assessing submarining and abdominal injury risk in the Hybrid III family of dummies

The development of an abdominal injury assessment device for belt loading due to submarining is detailed in this paper. The design concept was based on research assessing the effectiveness of safety belts with the Hybrid III dummies. The following conclusions were reached: The abdomen developed has biofidelity in its force-deflection characteristics for belt loading, and can be used to determine the probability of abdominal injury when submarining occurs; installing the abdomen in the Hybrid III dummy does not change the dummy kinematics when submarining does occur; when submarining does occur, the dummy kinematics are very similar to baseline Hybrid III kinematics, except for torso angle.

Assessing Submarining and Abdominal Injury Risk in the Hybrid III Family of Dummies: Part II - Development of the Small Female Frangible Abdomen

This paper describes the desin of the Frangible Abdomenn for the small female Hybrid III dummy and how to use it to assess the risk of abdominal injury from submarining. The baseline dummy and the dummy with the Frangible Abdomen have no significant kinematic differences, either qualitatively or quantitavily. Paper discusses the sled tests that were run to compare the kinematic and dynamic performance of the baseline dummy before and after the insertion of the Frangible Abdomen.
