The Porsche airbag module is an extension of the Madymo 2d simulation program version 4.0. It generates contact forces between the airbag and the contact cylinders and/or contact planes of the dummy or the vehicle interior respectively. The passive restraint system is calculated by means of a three-dimensional model. The simulated airbag shape is a realistic approximation of the actual airbag and can be arbitrarily defined within a large range.
The results were validated by numerous crash-, sled-, component- and inflation tests using different vehicles and airbag systems.
Good correlation between the results of the simulations and of comparable vehicle tests has been confirmed by many examples for both the driver and the front passenger dummies. The Porsche airbag simulation program is sensitive to variations of input parameters. The program and the data sets are easy to handle.
The present paper gives examples of driver's and passenger's side airbag simulations with various parameters and an example of a child out-of-position simulation.
Finally, the limits of airbag simulation in this program are explained.
