• Resumen

  • In transportation and use environments, electronic appliances, especially those that are large and heavy, suffer many different types of mechanical shocks. Generally, to prevent damage to the products from severe shocks, various cushion materials used for packaging have been widely utilized. However, the external shape of electronic appliances is complex, and the mass distribution of the inside parts is unbalanced. Consequently, it is not easy when using empirical approaches to design the cushioning package to ensure that it has a high absorption of shock energy. In this study, experimental and analytical approaches have been used to propose an effective design process for the optimization of cushioning packages so that they have less volume and a greater cushioning ability. An examination of the optimization of cushioning package was conducted for a large-size refrigerator with a weight of more than 100 kg to demonstrate the usefulness of the proposed method; findings from the study show that the volume reduction of a package was as much as 22% with the reduction of maximum acceleration at 25%.
