A New Approach for Folding Process Modeling of Passage Airbag

Abstract:

A new Passage Airbag (PAB) folding method which integrates simulation folding and manual folding is presented. Determining how to get a multi-layer 2D surface is vital to PAB folding. By means of 3D PAB flattening process simulation, 2D surface with a minimum area loss is created. This method avoids the traditional measurement of real PAB to obtain 2D airbag with inaccurate shape and size. After flattening PAB simulation, the 2D surfaces are meshed with respect to the predefined folding lines. The subsequent folding steps of flat 2D airbag are carried out according to the folding requirements. Finally, the reference geometry meshing and folded airbag are obtained accurately and rapidly. The static PAB deployment test is modeled using particle method for gas flow to validate this folding method. Good correlation between simulation and test results during early deployment phase of airbag is achieved. It has proven the effectiveness and feasibility of this PAB folding method.
