Analysis and Modelling of Vibration Performance for Multi-layered Corrugated Structure

Abstract

The purpose of this study was to analyze for resonant frequency, vibration transmissibility and damping ratio of multi-layered corrugated structures using a random vibration test. Methods: The random vibration test was performed by the ASTM D4728 specifications using two paperboards (S120, K180) and two types of flutes (A/F, B/F). Damping ratio of the multi-layered corrugated structures was estimated using a theoretical equation derived from the measured resonant frequency and transmissibility. Results: The resonant frequency and vibration transmissibility of the multi-layered corrugated structures of K180 and B-flute were higher than those of S120 and A-flute, respectively; however, the damping ratio of each sample had the opposite tendency. The resonant frequency was inversely proportional to the sample thickness and static stress; vibration transmissibility and damping ratio were not correlated with sample thickness and static stress. In addition, we developed a mathematical model of the resonant frequency with variables of sample thickness and static stress. Conclusions: Results of this study can be useful for environment-friendly and optimal packaging design since vibration has been a key factor in cushioning packaging design.

Mechanical damages and packaging methods along the fresh fruit supply chain: A review

“…The corrugated paper layers, flute type, and structure of CFB have been shown to influence the package's protective performance based on vibration tests (Jin et al, 2013) and compression tests (Frank, 2014). By using pressure-sensitive films, the pressurized areas and average pressures of apples in a single-wall CFB were determined to be larger than those in double-wall boxes (Fei et al, 2010).…”

Modeling and Analysis of Cushioning Performance for Multi-layered Corrugated Structures

“…In such packaging, the energy absorbing characteristics of flute are employed for protection against shocks and vibrations ( Kim et al, 2013). As shown in Figure 1, various types of MLCS packaging-edge pads (for angles), side pads (for channels), and face pads (for flat surfaces)-can be produced to suit the shapes of the products to be packaged.…”

“…Cushioning performance, vibration transmissibility, and compressive resistance of MLCS were examined in detail in previous works (Wang, 2009;Guo et al, 2011;Kim et al, 2013;Wang et al, 2013). Guo et al (2010) considered the shape of the shock pulse of the MLCS as a half-sine wave, and they approximated the cushion curve of the peak acceleration-static stress with a third-degree poly- nomial.…”
