| 摘 要： | 随着国内航运市场的旺盛，满足国内近海航区及南京以下长江各港口的国内贸易散货船应运而生。国内贸易散货船的受力工况和装载工况不同于常规CSR散货船，结构要求也有所不同。以46000DWT国内贸易散货船舱段结构的FEM直接计算分析为例，简单介绍了有限元分析计算过程中波浪载荷的选取、模型的建立和加载、分析的伞讨程．以及绎计算后对原结构的优化调整。

| Abstract: | With the blooming of domestic shipping market,domestic trading bulk carriers which met the requirement of the coastal area and the harbors of Yangzi River below Nanjing were coming up.Loading cases and structural requirement of domestic trading bulk carriers were different from CSR bulk carriers.In this paper,FEM analysis was performed on 46 000 DWT domestic trading bulk carrier,covering the whole procedure of wave load selection, structure and load modeling,and also structural optimization. |
