摘　　要：论文针对一条在建2200吨级的小水线面双体船,釆用规范载荷计算方法进行有限元分析,分别对各个工况组合进行屈服强度计算分析,并根据屈服强度计算的应力结果进行板格屈曲强度校核.总结各个浪向下工况组合的屈服强度和屈曲强度计算结果,分析全船结构受力特性,并对该船做出相应结构优化设计.研究结果可为小水线面双体船的整船结构设计提供参考.In the article , a finite element analysis is carried out for a 2200 tone SWATH ship with the specified calculation method by the rule. Yield strength is calculated under working conditions, and then buckling strength of the plate is checked with the stress result of the yield strength . Calculation results of yield strength and buckling strength under different wave conditions are summarized. Mechanical characteristics of the whole ship structure are analyzed, and optimal structural design is carried out. The research can provide reference for design of whole hull’s structure of SWATH ships.
