CPM Airbag Modeling

In addition to the ALE method for simulation of out-of-position load cases, which has been available for a number of years, the corpuscular method (CPM), which is based on a particle approach, was developed by LSTC for simulation of airbag deployment processes. This method is distinguished by extremely simple handling and reduced computing times compared to the highly variable and widely applicable ALE approach. Based on this molecule approach, it is now possible to set up simulations for OoP load cases in an extremely simple manner with just a few changes to the uniform pressure input file. Experience with the method has been excellent to date. The accuracy and efficiency of the method in particular are persuasive. It permits realistic calculations of many new load cases – to supplement the established ALE method.

 

The one day class presents basics of the new corpuscular method and a brief introduction on the ALE method. Emphasis is on the steps from a uniform pressure input to a simulation considering also the gas flow.
