摘要

船舶设备基座是将动力设备连接到船体上的结构。它必须具有较高的承载能力和承受较大冲击载荷的能力。本文提出了一种具有正负泊松比的新型结构。通过数值模拟分析了该结构在准静态压缩载荷作用下的变形机理和模式。在此基础上，设计了一种多孔基座，并分析了其承载能力和抗冲击能力。对基座的结构参数进行了优化。实验对基座模型的抗冲击性能进行了评估，证实了所提出的多细胞基座具有出色的抗冲击性能。

Research on the Load Bearing and Impact Resistance of a Novel Structure Exhibiting Both Positive and Negative Poisson’s Ratios

A ship equipment pedestal is a structure that connects power equipment to a hull. It must have a high load-bearing capacity and the ability to withstand large impact loads. In this paper, a novel structure with a positive-negative Poisson’s ratio is proposed. The deformation mechanism and mode of this structure under quasistatic compression loading are analysed via numerical simulation. Based on this new structure, a multicellular pedestal is designed, and its bearing capacity and impact resistance are analysed. The structural parameters of the pedestal are optimized. An experiment is conducted to evaluate the impact resistance of the pedestal model, which confirms that the proposed multicellular pedestal exhibits excellent impact resistance.
