Modeling and Simulation of OOP Occupant-Airbag Interaction

This paper presents efforts made on the computational modeling and simulation of our-of-position occupant-airbag interaction. The airbag has been modeled using the finite element method with LSDYNA. The investigation in this paper shows that the integration of an FE airbag model with an ATB occupant model is a feasible and effective way of modeling and simulating the biodynamics of an occupant-airbag system. It takes the advantages of the detailed modeling of the airbag provided by FE and the efficient modeling of the occupant provided by ATB. The use of the integrated model in the simulations of unbelted occupant sled impact and static OOP deployment impact has produced fairly realistic demonstrations of the kinematical responses of the occupant.
