Abstract


For heavy and expensive electro-mechanical products, wooden package is still widely used in the most important transportation and distribution packaging. In wooden transport packaging system, the wooden structure and cushioning pads have different functions on the cushioning performance of the system. The cushioning properties of EPE or EPS cushions are usually fully considered, the buffer performance of wood base structure is often ignored. In this work´╝îconsidering the overall performance of wooden base structure and cushioning material, the EPE (Expandable Polyethylene) liner is designed based on the classic cushioning packaging theory. Then the simulated drop analysis was carried out on the wooded structure, EPE buffer liner and the composite structure using the DTM (Drop Test Module) module of ANSYS/LS-DYNA. The results showed that the cushioning capacity of wood materials was poor, but the cushioning properties of wood based materials were improved. The EPE liner plays a major role in cushioning performance of the wooden transport packaging system. The combination of wooden base and EPE liner exhibites better cushioning performance. The research results can guide the reduction design of the wooden transportation packaging system.
