Abstract: Sandwich plate system(SPS) with superior mechanical performance has been widely used in ship repairing. The core has good buffer function so that it can be used as crashworthiness structures. Based on ABAQUS, the crashworthiness of SPS under collision load was analyzed, such as damage deformation, collision force and energy absorption. Then the crashworthiness of SPS was compared with stiffened plate and folded sandwich panel. At last, the influence of structural parameters on the crashworthiness of SPS was analyzed. The results show that SPS has better crashworthiness than the other two structures. Structural parameters have effects on the crashworthiness of SPS to some extent. With face thickness rising, the energy absorption of upper and lower faces rises obviously, while the specific energy decreases. With core height rising, the energy absorption of upper face and core rises obviously, and the specific energy of upper face rises fastest.
