A Methodology for Modeling Confined, Temperature Sensitive Cushioning Systems

摘要

A methodology for modeling the impact response of a confined cushioning system has been demonstrated. Data for modeling were acquired from test drops made with a test specimen comprised of a plywood cube (protected item) within a cleated plywood shipping container, under controlled environmental conditions, utilizing 2-inch Minicel as the cushioning system. Individual curves were developed for each temperature and drop height for both the interior box and total container system. Utilizing a stepwise regression procedure, a general model was developed for the interior box and also for the total container system. The general model permits the cushion designer to predict the impact response of a container system within drop heights of 12 to 30 inches, a temperature range of -65 F to 160 F, and a static stress range of 0.088 to 1.255 psi.
