超大型液化石油气船结构强度分析

Structural Strength Analysis of the Very Large LPG Carrier

以超大型液化石油气船为研究对象,结合规范计算与有限元方法,分析货舱区主船体与A型独立舱的构件尺寸确定方法,评估各区域结构的安全性并给出结构加强建议,并确定A型独立舱支撑与制动装置布置方式。

Taking a very large liquefied petroleum gas(LPG) carrier as the research object,combined the regulation calculationwith the finite element method,the method for determining the scantlings of members in cargo area of the main hull and the type A independent tank was investigated. The structural strength of various kinds of members was assessed,to put forward some strengtheningadvices. Thearrangement method of supports and chocks for cargo tank was also determined.
