Sensitivity Study of Occupant Response in Simulated Crash Environment 740117

The sensitivity of response of crash victim simulation was investigated using a two-dimensional, mathematical eight-mass model. The model was exercised in the forward collision mode in a three-point restraint system using a trapezoidal forcing function. Mass and inertia parameters of the occupant simulation, its setup, and the restraint and environment systems were evaluated individually and as groups, in terms of their effects on the occupant's head and chest acceleration. The study also investigates and rates the effects of shape and time duration of the forcing function upon the response of the occupant.
