Advanced Methodology for Predictable Out-of-Position Simulation

The development of occupant safety systems does not only require an accurate numerical In-Position model but also an Out-of-Position (OoP) simulation model. To meet the needs of OoP simulation Takata-Petri developed an advanced methodology to ensure a faster, better and more efficient system development. This methodology includes basically the device for thrust measurement, the Out-of- Position Pendulum, the ESI Sim-Folder and the CPM-Method. A lot of tests were conducted with flat and folded airbags. It could be proved that the numerical OoP models are able to predict the effects of folding pattern modifications. Although many additional challenges should be set, OoP simulation is not far away from a fully integrated development tool equal to current tools for In-Position simulation.
