摘　　要：不同于常规船型的LNG船,A型LNG船的独立菱形液舱与船体间通过支撑系统有效连接。本文详细介绍了支撑系统的5种支座结构形式。结合ABS rules,运用Ansys软件对船体进行三舱段总体分析,用弹簧单元模拟层压木刚度,分析比较在危险工况下的5种支座受力,并优化安装位置,为类似A型LNG船的支承系统提供一定的参考。Different from conventional ship, independent rhombic tank of A-type LNG ship is effectively connected with the hull by the support system. In this paper, there are 5 types of structural forms of supports and chocks are introduced in detail. According to ABS rules, in this paper, it uses Ansys software to analyze three cabin of the hull,simulating stiffness of laminated wood with spring element, comparing and analysizing force acting on five supports under more dangerous load cases, and optimizing the installation position, which provide a reference for similar support system of A-type LNG ship.
