This article deals with the characterization of dynamic packaging properties of corru-gated paperboard pads, such as dynamic cushioning curves, vibration transmissibility and frequency curves. The main feature of article is the evaluation on the dynamic shock cushioning property and vibration trans-missibility of corrugated paperboard pads by a series of experimental studies on the drop shock tester and vibration tester, the establishment of experimental formulas of dynamic cushioning curves, and the analysis of resonance frequencies and vibration transmissibility. By using the fitting polynomial of curve and method of the least mean square, the experimental formulas with third order polynomial function of dynamic cush-ioning curves for corrugated paperboard pads are obtained. By using linear vibration theory with single de-gree of freedom, the resonance frequencies, vibration transmissibility and damping ratios of corrugated pa-perboard pads at different static loads are acquired. All results show the dynamic properties relevant to de-sign applications of corrugated paperboard pads for protective packaging.展开更多
