Energy Requirements - Correlation Between Occupant, Bag and Inflator 720415
Part I of this paper discusses a computer model of a hybrid air cushion inflator which models existing systems to a high degree of accuracy. Gas generator size and ballistic properties, stored gas composition, storage pressure, volume, temperature, and receiving tank parameters can be varied to accurately predict the effects of system changes on inflator performance.
In Part II, an approach for analytically obtaining equations of motion for torsos during contact with gas cushions in frontal collisions and subsequent ride-down characteristics is developed. From these equations, calculations of torso “g” forces, cushion pressures and other system parameters can be made. It is then possible to optimize these parameters in terms of desired torso response under a variety of design criteria as a guide to system design and experimental verification.
