【Abstract】 The work aims to design a multifunctional product packaging simulator for transportation packaging experiments and packaging dynamics research, to simulate the drop impact behavior of products with key components and evaluate the protective performance of cushioning materials, so as to meet the requirements of both academic teaching and scientific research. The application requirements for testing transportation packages were analyzed. A design scheme was proposed, dividing the multifunctional product packaging simulator into two parts: the main structure and the key components, followed by its physical fabrication. With Expanded Polyethylene(EPE) as the cushioning material, a series of package drop tests were conducted to investigate the application effectiveness of the simulator and the influence of the cushioning material on the free-fall impact response. Free-fall impact tests were performed separately on the simulator’s main structure and on the complete packages containing the key components. The obtained impact acceleration-time curves and the maximum impact acceleration values were consistent with data from relevant literature. The multifunctional product packaging simulator can effectively simulate the response characteristics of products with three key components under free-fall impact. It achieves the objective of directly understanding the protective effect of cushioning against product drop impact through data analysis. Furthermore, it facilitates further experimental research into the influence patterns of cushioning materials on the impact response of packages during drops.更多还原
