3200m^3LPG运输船鞍座结构强度计算与分析

Calculation and analysis of structure strength of saddle-base for 3200m^3 LPG vessel

依据《散装运输液化气体船舶构造与设备规范》,建立有限元模型,对鞍座结构受静、动载荷作用时的结构强度进行了计算,得到六种不同工况下鞍座结构强度计算结果,并对计算结果进行了分析.同时文中介绍了许用应力强度衡准,提出了作用于鞍座表面上的力按正弦和余弦函数形式分布,为类似鞍座结构强度与分析提供一定的参考.

According to the ＂Rules for the Construction and Equipment of Ships Carrying Liquefied Gas m Bulk＂, the finite element models are created The structure strength is calculated when the saddle-base is imposed by the static and dynamic loads. The calculation results of structure strength m six working conditions are gamed and analyzed At the same time, the paper introduces the strength criterion of allowable stress, and pomts out that the forces imposed on the surface of the saddle-base distribute as sine and cosine function. The paper gives certain reference to structure strength calculation and analysis of such saddle-base.
