摘　　要：三体船的总载荷较为复杂,为保证船体的安全性,有必要对其设计载荷的确定和结构强度校核进行分析。以某型三体船为研究对象,采用规范计算、波浪载荷软件预报和模型试验相结合的方法进行总载荷设计。总结该型船横向载荷与纵向载荷的关系,采用全船有限元方法对其进行结构强度校核,分析三体船结构的高应力区域,为后续同类型船的设计提供参考。The global loads of Trimaran are complicated,so it is important to decide the design load and make strength check to ensure hull safety.A trimaran is taken as the project to carry out the global loads design on the basis of the rule calculations,software prediction of wave load and model tests.The relationship between transversal loads and longitudinal loads are summarized,and the global finite element method is used for structural strength check to analyze the high stress regions of the trimaran structures.This provides reference for the design of subsequent ships.
