1. the method for a simulating vehicle inflatable supplemental restraint system may further comprise the steps:

  • Use a finite element model to simulate the restraint device of complete inflated condition;

    Utilize the data of the complete inflated condition of simulation in the implicit expression finite element model, the restraint device of this simulation is changed into venting and state of applanation fully from complete inflated condition;

    AndThe result that will meet fully venting and state of applanation, comprise the finite element grid data that meet venting fully and state of applanation and geometric data be input to a finite element model with simulate this restraint device from exit fully and state of applanation to the folding process of folded state.
