Method for designing air bags on lateral front side of automobile driver

The invention discloses a method for designing air bags on the lateral front side of an automobile driver. The method includes the steps: 1, setting up an air bag analytical model, namely determining the relation between the impact block acceleration and the air bag internal pressure, and between the contact area of the impact block with the air bag and the impact block mass; determining an air leakage speed expression; and setting up the air bag analytical model; 2, designing main parameters of the air bag, namely determining main parameter design initial values of the air bag; substituting the main parameter design initial values into the analytical model to work out an impact block acceleration response curve; and assessing the impact block acceleration response curve to determine mainparameter design values; 3, subjecting the air bag to computer simulation analysis, namely determining other air bag parameter design initial values; using MADYMO software to set up a computer simulation analysis of the air b
