Temperature Sensitive Dynamic Cushioning Function Development and Validation for BLOCKSOM Rubberized Hair.

Abstract

After acquisition of drop test data on the cushioning performance of Type V Rubberized Hair, an Analysis of Variance (ANOVA) was conducted which was based upon the split-split plot experimental design to establish the statistical significance of the temperature effect. Drop height, temperature, thickness, and static stress, the temperature effect was highly significant at the 5% level of significance. This, of course, means that it is possible to reject the null hypothesis that temperature has no effect upon cushioning performance of this material for all four drop heights. After the temperature effect was proven significant, the data was input to the curvilinear regression computer program. Once again, the parabolic-logarithmic fit was determined to be best for predicting the deceleration at impact of a packaged item.
