Development of a Hybrid III 5 ^th Percentile Facet Dummy Model

A MADYMO multibody model of the Hybrid III 5^th percentile female dummy has been developed. Most attention is placed on modelling the thorax, pelvis-abdomen, head and neck. Those parts are modelled with facet surfaces and deformable bodies are used for the thorax. The remaining dummy parts are identical to an existing ellipsoid model.

The facet component models have a more detailed geometry and are therefore more realistic than the ellipsoid model. The model enables accurate interaction with a FE lap belt, or seat, or airbag.

The dummy model has been tested and validated using component tests and full dummy tests. From the results, it can be concluded that the model is an improved tool, which will give engineers more confidence concerning predictability. The model is slightly slower than the ellipsoid model, but still fast enough to perform parametric studies and optimizations.
