abstract="In this research, a model and a particle simulation method were used to analyse the stiffness of a fully deployed airbag that is related to the severity of the occupant injury in a frontal crash. First, a mathematical model based on a three-dimensional airbag geometry was introduced. Then, quasi-static and dynamic test setups were defined, including an external impactor to simulate an actual crash. A simulation was also designed by the corpuscular method with the same initial conditions to validate the airbag model and to assess the effect of parameters at the out-of-position (OOP) impact. Finally, airbag stiffness characteristics were calculated for different airbag capacities and inflator performances as a function of internal pressure and volume. The evaluated time-dependent stiffness characteristics were linearised by the proposed method. The estimated coefficients were correlated to airbag geometry and inflator performance and can predict occupant injury in a high-speed crash.<p /> <p>Language: en</p>",
