Analysis and Evaluation of the Biofidelity of the Human Body Finite Element Model in Lateral Impact Simulations According to ISO-TR9790 Procedures

An analysis and evaluation of the biofidelity of the Ford Motor Company human body finite element (FE) model in side impact simulations was conducted according to the procedures outlined in ISO technical report TR9790. The FE model represented a 50th percentile adult male. It was used to simulate the biomechanical impact tests described in ISO-TR9790. These tests were considered as suitable for assessing the lateral impact biofidelity of the head, neck, shoulder, thorax, abdomen, and pelvis of cash test dummies, subcomponent test devices, and mathematical models that are used to represent a 50th percentile adult male. The simulated responses of the FE model were compared with the PMHS (Post Mortem Human Subject) data upon which the response requirements for side impact surrogates was based. An overall biofidelity rating of the human body FE model was determined using the ISO-TR9790 rating method. The human body FE model was rated 8.5 on a 0 to 10 scale with 8.6-10 being excellent biofidelity. To explore possible dependency of the impact responses of the FE model on different analysis codes, three commercially available analysis codes (LS-DYNA®, Pamcrash®, and Radioss®) were used to run the human body FE model. The effects of these codes on biofidelity, compared with ISO-TR9790 data, are discussed. Also discussed are model robustness and numerical issues arising with three different code simulations.
