Abstract

This paper describes a finite element model of the Hybrid III thorax, which is applied in conjunction with a Hybrid III dummy model using the LS-DYNA3D code. The model reproduces the geometric and physical properties of the Hybrid III and permits the measurement of chest deflection in five locations. The locations coincide with the centre measurement in the Hybrid III and the four measurements proposed in the new TAD-50 dummy. The model allows the evaluation of loading by belts, air bags, and combinations. The paper summarizes baseline tests of the Hybrid III in which the restraints were three point belts, air bags, and belts combined with an air bag. These tests are used to calibrate the FEM. The model results indicate how NHTSA's newly proposed injury criteria (based on five deflection measurements) compares with existing criteria (based on centre of gravity acceleration and centreline chest deflection).
