摘　　要：针对一艘新型高速M型船结构设计过程中的强度问题,参照相关规范,采用有限元方法进行计算分析,获得本船在危险工况下的船体结构特别是M型连接桥底板结构的应力状态和变形形态,为结构优化设计提供依据.研究结果表明,本船船体结构特别是底部连接桥遂道部位、甲板大开口部位的应力状态良好,构件变形较小,均没有出现应力集中和大变形的现象,验证了结构设计的合理性.In view of the strength problem in the structural design of a new type of high-speed M-boat, finite element calculation was carried out with reference to relevant codes,and the stress state and deformation form of the hull structure,especially the bottom plate structure of the cross structure,under dangerous conditions were obtained,which provides the basis for structural optimization design of M-form hull.The result shows that the stress state of the hull structures,especially the cross-structure and the large deck opening region,is good.The deformation of the components is small,and there is no stress concentration phenomenon,which verifies the rationality of the structural design.
