【摘要】：针对HCSR对于局部结构强度细化分析子模型范围的规定及CCS_HCSR_TOOLS对于细化分析子模型边界条件施加方法的合理性问题,以某散货船的底边舱下折角为例,进行局部结构细化网格分析,分别建立嵌入式细化模型以及3个不同范围的子模型,以嵌入式模型计算结果为基准,对比各子模型应力计算结果表明,子模型范围、边界节点角位移约束及子模型新增节点的插值处理对应力结果影响较大;子模型边界节点所在位置对应力结果影响不大。
[Abstract]:In view of the rules of HCSR on the scope of submodel of local structural strength refinement analysis and the rationality of applying method of CCS_HCSR_TOOLS to submodel boundary conditions of submodel refinement analysis, this paper takes the underside angle of a bulk carrier as an example. The local structure refinement mesh analysis is carried out, and the embedded refinement model and three submodels with different ranges are established respectively. Based on the calculation results of the embedded model, the stress calculation results of each sub-model are compared and the results show that the sub-model range. The angular displacement constraints of boundary nodes and the interpolation treatment of new nodes in sub-model have great influence on the stress results. The location of the boundary nodes in the sub-model has little effect on the stress results.
