Accurate and Detailed LS-DYNA FE Models of the US- and EUROSID: A Review of the German FAT Project

Finite element side impact dummy models of the USSID and EUROSID are of major interest for industry, as more detailed models are required for better prediction capabilities, but still efficiency has to be maintained to some degree. Both type of models, the so-called FAT- USSID and FAT-EUROSID have been developed by CAD-FEM in cooperation with the German Association for Automotive Research (FAT). The main objective was to achieve highly validated finite element models. During the development process the models are vali- dated at three levels: material, component and assembly and tested finally by sled test appli- cations. Additional input was provided by other type of simulations from the LS-DYNA users within the FAT. This paper summarizes the experience gained during the validation and optimization process which may be used as a guideline for an efficient methodology to generate reliable finite element dummy models. Finally, the good performance of the current USSID and EUROSID models is presented for some selected tests.
