To protect products from shock and vibration during transport, Cushioning Packaging Design is implemented. The cushioning performance and anti-vibration performance of a package is tested by a drop test and a vibration test. The effectiveness of the cushioning during a drop test is predictable because the cushioning material`s thickness and bearing area are determined by the cushion curves which are plotted based on the results of the tests. However, an effective package-design method which can predict the package vibration of all the static stresses that are suitable for cushioning package design has not been established yet.thus, it remains uncertain until actually vibration tests are conducted and redesigns are developed to correct the failures during the tests. Redesigning efforts are expensive and time consuming. Therefore, in this study, we propose the “Hybrid Damping Package Design” wherein both the Cushioning Packaging Design and the Anti-vibration Package Design will be implemented. In particular, Multibody Dynamic simulation is applied as an aided design tool for Anti-vibration Package Design so that numerical analysis a package’s vibration response becomes possible. Furthermore, we discuss a case study to demonstrate how to analyze and compare multiple package designs in order to determine the best candidates based on cushioning performance, anti-vibration performance, and material cost.
