Finite Element Model Development of the BioSID 971140

A complete finite element model of the BioSID side impact dummy was created using the finite element code RADIOSS. The objective of this work was to develop an accurate and stable dummy model, which can capture the dummy behavior due to a localized impact or in a full-scale side impact finite element model with reasonable CPU time. This warranted the development of a detailed dummy model which reflects the BioSID geometrically and has material characteristics similar to the physical dummy. This paper describes the stages of the model development and discusses the issues which influence the accuracy of the dummy model predictions. It also shows comparisons of the dummy model responses and kinematics with a series of sled test data and calibration tests specified in the BioSID User's Manual.
