摘要

The effect of moisture content on the cushion curves for Honeycomb was investigated and a mathematical approach aimed at the development of a model to predict the peak acceleration was attempted. Two different cell sizes of Honeycomb having various moisture contents were used to determine static crushing strengths and dynamic shock transmission values for three different drop heights at seven different static stresses. The two mathematical models attempted were the adiabatic air compression model and an energy approach based on a dynamic extension of the static stress strain curve. Because of the complicated structure of Honeycomb, neither model provided accurate results and it was therefore concluded that modelling was impractical. A curve fitting approach which resulted in a high degree of correlation with the experimental data was used instead.
