海洋平台建模的问题?

yuan_xinqing

请问高手或专家: 对于海洋平台进行实体建模时,用什么软件最好,最方便? 例如对于自升式平台,是用hypermesh?还是patran,还是应用ANSYS或ABAQUS自带的前处理功能建模呢?

请有经验的高手给予解答!!!!并讨论各前处理软件在海洋平台建模时的优点和缺点..........

我也建过海洋平台，感觉用PATRAN比较方便，而且动、静态分析也比较准确合理！

做整体分析是可u以用sacs，计算量小，对于局部的校核可以采用有限元软件，很方便。
可以做地震、冰载荷、流、波浪等等。

你试试ANSYS吧，下面是模型的APDL命令流！

各有优缺点，熟悉一门软件就可以

ansys建导管架平台的模型是没有问题，但是做半潜式平台，常规船呢，曲率变化较大的部分怎样处理

sim_lgdlp123

CATIA：建模速度快，可多人同时建模，网格划分较麻烦
ABAQUS:建模有点慢，但最新6.8版，可组合cae文件，也可多人建模，后期使用子模型进行LOACAL 分析优势明显

axevious

建模分析，加载
需要专门处理
通用软件不足很多
可以尝试使用专用软件
