A Statistical Investigation into the Development of Energy Absorber Design Criteria.

Abstract

A Statistical technique for evaluating the injury reduction capability of energy absorbers was developed. Existing statistical data on crash accelerations and man-weight distributions were used as inputs to a MIMIC computer program. A Dynamic Response Index (D.R.I) and stroke length were computed for each acceleration - man-weight combination. The joint probability for each acceleration, man-weight, DRI combination was figured. The summation of all such combinations produced a cumulative probability of injury for the specific energy absorber. The waveform of the force deflection curve of the energy absorber was varied to determine the effect on cumulative probability of injury and required stroke length. The results of the program can be used as a guideline in selecting candidate energy absorbers and the technique developed is appropriate for evaluating the absorbers so selected. (Author)
