Development of special new versions of the FAT/PDB Dummy models for quick analysis response. The Rapid Analysis Models (R.A.M.)

The finite element model of the FAT and PDB Dummy models have been developed in co-operation with the German Automotive lndustry for the last few years, One of the major goals during the development of the models was to achieve a high degree of accuracy of the model as well as to have a robust model without numerical instabilities. During the course of the model development, the geometry of various components has evolved considerably and finite element meshes for the various components have gotten finer. New material tests were also carried out for many components resulting in the use of advanced material models. This has naturally resulted in an increase in the computation times for the model. Increased computation times are definitely a hindrance when it comes to carrying out a studywith a large sample set for example. Keeping this in mind, we at DYNAmore have developed a simplified version of the ES-2IES-2re model meant for rapid prototming. This simplified model requires considerably lesser computation time and delivers extremely good results in the component and barrier tests, considering the degree of simplicity of the model. The geometry of the model has remained unchanged. Simplified and "quicker" materid models have been used wherever possible and all the certification and component tests were carried out for the model. Development of a R.A.M. model of the WorldSID 500b has also been started. As a final step, the soffware CORA [1J (CORrelation and Analysis) waas used to obtain an objective comparison of the simplified model to the original model.
