The Impact Property of Cargo Hatchcover with Steel-polyurethane Sandwich Plate

Lin Wang, Gan Su, Yiming Huang Yiming Huang


Steel-Polyurethane sandwich plate, a new composite material, which has features of light, impact resistance and well-heat insulation, had been widely used in ship manufacturing and repairing. The main aim of this issue are offering a reference for hatchcover design and manufacture. This issue mainly used Dytran to carry out a finite element numerical simulation and analysis the deformation and energy absorption on adapting SPS hatchcover and steel structure hatchcover, then made a comparison. At last, as the limits of impact conditions, the advantages were not very large but the analysis still shows that the SPS has a good prospect in ship manufacturing.
