DEVELOPMENT OF THE DEPLOY COMPUTER MATH MODEL FOR THE INVESTIGATION OF VARIOUS AIRBAG AND CRASH PARAMETERS ON THE OUT-OF-POSITION OCCUPANT

This program is based upon a previous program known as "Bagslap" and is expanded and improved over the original version. A chest surface mass has been added. The bag deployment algorithm improved, and additional output provided. The program computes the interaction of a normally seated or an out of position passenger with a deploying airbag in a crash or non-crash situation. The user specifies certain variables such as bag shape and volume, bag weight, vent area, vent actuation pressure, passenger weight, weight of chest surface, impact velocity, chest width, gas flow parameters, chest surface and chest overall force-displacement parameters, crash pulse and a few other parameters. The program then computes the dynamics of the interaction of the deploying airbag and the passenger. Typical output would be the accelerations of the passenger, The airbag and both chest masses; the velocity of the vehicle, passenger, airbag, and the masses; the displacement of the vehicle, airbag and the chest masses; as well as the other parameters of interest such as chest penetration of the airbag, Pressure in the bag, volume of the bag, mass rate of flow of gas exiting the bag, and the chest forces.
