摘要
本文分析了小水线面双体船波浪载荷预报的几种方法 ,比较了准静态法、刚体动力学法、水弹性法、经验公式法的优缺点 ,讨论了结构有限元离散的注意事项 ,以及斜支柱结构形式对动载荷和疲劳的有利因素。并对全船进行了有限元应力分析 。
The paper analyses several predicting methods for wave load acting on SWATH ship and compares the advantages and defects of quasi static method, rigid body dynamic method, hydro elasticity method and empirical formula method. The matters needing attention in finite element discretion of structure and the favorable factors of diagonal stanchion structure type for dynamic load and fatigue are discussed. Meanwhile, a finite element analysis for whole ship has been given. The stress responses of overall ship and stress distribution feature in stress concentration area have been got.
