摘要
通过研究横撑的受力特征,提出了一种新的中心对称的横撑结构形式,推导了其剖面属性的计算公式,并据此设计了一种少横撑结构的超大型油船中部货舱结构布置形式,根据最新《协调共同结构规范》进行了直接强度评估,利用ABAQUS非线性有限元计算软件分析了中心对称横撑结构的抗屈曲特性。
A new centrosymmetric section is proposed based on the mechanical characteristics of cross tie, and the corresponding formulae for cross sectional properties are derived. Few-cross-tie design with centrosymmetric section in mid-region cargo of VLCC is developed and verified using finite element analysis complied with CSR-H. Finally, the global buckling capacity of centrosymmetric cross tie is evaluated by ABAQUS software.
