Modeling and Simulation of OOP Occupant-Airbag Interaction 2003-01-0510

This paper presents efforts made on the computational modeling and simulation of out-of-position occupant-airbag interaction. The airbag was modeled using the finite element method with LSDYNA. Static airbag deployment tests were performed to support and validate computational modeling efforts. A 50-segment rigid body model was developed for the 5th percentile Hybrid-III female dummy using the Articulated Total Body (ATB) model program. This occupant model allows for the detailed simulation of occupant responses in several body regions. The system that describes out-of-position occupant-airbag interaction in frontal crashes, including airbag, occupant, and major vehicle structures, was modeled through the integration of the rigid body occupant model with the finite element airbag model using the function provided by LSDYNA. The biodynamics of the occupant-airbag interaction were simulated for unbelted occupant sled impacts and two out-of-position static deployment impacts.
