ABSTRACT

The basic operation of convolution theory, the derivation of the transfer function, and an algorithm using a snow-ball effect to increase the computation efficiency are discussed. Cases are presented which include but are not limited to the (1) Use of transfer functions in assessing the occupant response prediction using various crash pulse approximations, (2) Characterization of truck body mounts by FIR coefficients and the prediction of body pulses with different frame pulses, (3) Evaluation of the performance of air bag and steering column restraint systems for both unbelted and belted occupant responses, and (4) Assessment of sled test pulses and the prediction of its occupant crash severity in a barrier test condition.
