摘要
运用有限元方法,采用薄壳单元、弹性梁单元和薄壁圆管单元建立了斜船架混合单元有限元模型。理论计算结果与试验测量数据对比较为吻合,证实了该模型是可行的。在此基础上,提出了结构优化设计方案并进行了计算分析与对比。
In this paper, structural load ability of the ship girder in a large domestic ship yard is analized. Different types of element such as shell, beam and pipe element set up FEA model of the ship girder. The FEA data fits well with the test data and proves the model to be applicable. Based on this, the improved design structure is put forward and analyzed for comparison.
