Abstract
The work aims to simulate the static pressure conditions of Huangguan Pears during logistics transportation and investigate the static mechanical properties and damage of Huangguan Pears packaged with Expandable Polyethylene (EPE) net in the transverse, longitudinal, and oblique directions. The methods adopted mainly included quasi-static compression experiments on Huangguan Pears and finite element analysis. The relative errors between the simulated and experimental results in the transverse, longitudinal, and oblique directions were 1.21%, 5.49%, and 5.55%, respectively, validating the accuracy of the finite element model. Compared to unpackaged Huangguan Pears, under transverse, longitudinal, and oblique static pressure, the initial displacement at which EPE-packaged Huangguan Pears experienced initial damage increased by 3.5 times, 2.9 times, and 2.3 times, respectively. At a compression displacement of 15 mm, the static pressure borne by EPE-packaged Huangguan Pears decreased by 76.1%, 74.4%, and 51.0%, respectively. When Huangguan Pears were compressed to the point of rupture, the static pressure borne by EPE-packaged Huangguan Pears increased by 17.9%, 14.9%, and 21.5%, respectively, and the resistance to external deformation increased by 1.9 times, 1.8 times, and 1.7 times. The damage area and volume percentages for EPE-packaged Huangguan Pears remained below 5%. The EPE net demonstrates a significant cushioning effect under static pressure, enhancing its static pressure-bearing capacity, reducing static pressure damage, and providing valuable insights for the design of cushioning packaging for Huangguan Pears, as well as minimizing losses during harvesting.
