150000DWT油船中剖面结构优化

On Structure Optimum of 150 000DWT Oil Carrier

文章针对150000DWT苏伊士原油船,按专家经验和结构优化相结合的原则,用ANSYS软件进行实体建模、划分网格,然后查取DNV规范的有关章节,提取公式,最后得出两种典型、危险工况下的载荷分布情况,将载荷加在实体模型上,用ANSYS软件特有的优化选项进行优化,迅速获得较优而实用的中剖面结构。

In this paper, the object is 150 000DWT Suez Crude Oil Carrier. According to the combination principles of experts＇ experience and structure optimum, the software of ANSYS is utilized to create the model, plot the grid, and then check the relative chapter of DNV Rule, obtaining the formula. At last, the two typical and hazardous conditions of load cases are deduced, by putting the loads on the model, being optimized by the special function of ANSYS, and obtaining an optimum and useful structure of mid-ship section quickly.
