“Relaxed” HBM – an Enabler to Pre-Crash Safety System Evaluation

This research addresses relaxation of existing human body finite element (FE) model, i.e. classical THUMS‐D in LS_DYNA. The methodology discussed identifies proposed corridors for relaxation; modifications carried out to model pertaining to relaxation and verify the simulations based on 1 g frontal braking pulse. “Relaxed” THUMS‐D delivers fairly good response in terms of head excursions. This model is able to deliver a response within the defined corridors after inclusion of Active Muscles. The modifications carried out to the model comprised of elastic moduli, connection in head‐neck complex and connections between spine and skin. “Relaxed” THUMS‐D model in totality delivered more head excursions compared to the defined corridors without any muscle activity.
