Characteristics of Vibration Transmissibility for Corrugated Paperboard

Corrugated fiberboard are typically lightweight and inexpensive with high stiffness-to-weight and strength-to-weight ratios as an environmental-friendly packaging materials. In order to optimize the application of corrugated paperboard for packaging cushioning materials, it; is essential that both a vibration transmissibility test and drop shock test; be completed for the transmissibility-frequency curve and dynamic cushion curve respectively. This paper deals with the characterization of properties of corrugated paperboard relevant to its application for protective packaging in transportation, such as vibration transmissibility, resonant frequency, clamping ratio, and maximum dynamic stress. The main feature of the paper is the evaluation on the vibration transmissibility of corrugated paperboard with corrugation shape and the equilibrium atmospheric conditions by a sinusoidal sweep vibration test. Additionally, clamping ratio and maximum dynamic stress were evaluated by linear vibration theory. All the works provide basic data relevant to its application for protective packaging in transportation.
