摘　　要：以中国船舶科学研究中心开展的200t至3500t多艘SWATH船模试验结果和美国的15艘从3000t至30000t小水线面双体船波浪载荷模型试验资料为基础,给出了小水线面双体船波浪设计载荷估算公式。用该估算公式算得的小于3000t的小水线面双体船的波浪设计载荷的估算值更加接近模型试验结果,而小于目前常用的ABS公式估算值,从而可较大地减轻结构质量和建造成本。根据小水线面双体船受力特点,还提出了小水线面双体船在进行横向强度、扭转强度、总纵强度校核时各种载荷的组合方案和施加方式,供结构设计人员全面、合理地进行强度分析参考。Based on the model test results of SWATH ship accomplished by CSSRC and America, a regresse formula was provided in this paper to evaluate the design wave load of SWATH ship. The formula gives more accurate design wave load which is close to the model test results in the case of lower displacement less than 3000t. Consequently the hull structure weight and fabrication cost will be reduced greatly. Based on the mechanical characteristic of SWATH ship, load combinations and loading manners are also presented in this paper for transverse strength analysis,torsion strength analysis and overall longitudinal strength analysis of SWATH ship.
