Cushion packaging design for maritime transportation: a new model based on stress-strain curves

Maritime transportation demands robust packaging solutions to protect goods against impacts, vibrations, and environmental conditions unique to sea travel. Traditional cushion packaging design relies on drop tests to generate cushion curves, a time-consuming process that lacks flexibility for the rapid demands of the industry. This paper proposes a novel cushion packaging design method based on stress-strain curves and energy conservation principles, which bypasses the need for extensive drop testing. Our approach is validated using ANSYS explicit dynamics simulations and experiments, showing compatibility with maritime transport conditions and efficiency in model generation. Results indicate that this new method provides a reliable, adaptable alternative for cushioning design in maritime logistics, promoting both durability and efficiency.
