Effect of Fatigue Vibration on Load Capability and Cushioning Performance of Corrugated Fiberboard
As a basic load and cushioning material in transport packaging, the corrugated fiberboard is ofgreat importance in its performance. The vibration during transport could cause fatigue damage on corrugatedfiberboard whose corresponding performance will then be changed. The fatigue vibration test was conductedon A-flute corrugated fiberboard with an acceleration of 0.5-2.0g and a frequency of 20Hz, after which thequasi-static compression tests and impact tests were carried out to measure the load capacity and the impactacceleration. The result showed that the residual yield stress of the corrugated fiberboard was remarkablydecreased with the increase of the vibration times and intensity, which results in the decline of its cushioningperformance. A new residual load capability model of the vibrated corrugated fiberboard was proposed,based on the residual intensity model. The change of stress-strain and cushioning coefficient for thevibrated-boards was studied based on the impact test data. The three-dimensional relation of maximalacceleration versus static stress and vibration times and dynamic cushioning coefficient versus maximalstress and vibration times were obtained analyzing the influence of different vibration times on the corrugatedfiberboard in its maximal acceleration and cushioning coefficient. The effect of fatigue vibration on theproperties of the corrugated fiberboard should be considered when doing the cushioning Packaging design.
