摘要: |
在蜂窝夹层板强度设计中,为了降低计算成本,并得到准确的计算结果,需要对蜂窝夹层板进行有效的等效建模。以简化的仪器安装板为例,对比研究了等效板、三明治夹芯板、三明治实体夹芯板和蜂窝体夹芯板4种强度分析模型,并基于蜂窝体夹芯板计算模型,对4种强度分析模型下的变形、应力和频率计算结果分别进行了对比研究,得到计算精度、适用范围等工程结论,同时形成相关软件应用界面,指导飞行器结构设计。 |

Abstract: |
A strength analysis model for the honeycomb core composites has to be facilitated to reduce calculation cost, at the same time ensuring calculation accuracy. The comparison among models of equivalent panel, sandwich panel, sandwich solid panel and honeycomb core panel is studied on one simplified instrument board. Engineering conclusions based on honeycomb core panel model about accuracy, scope of application, are drawn in respect of displacement, stress and modality results from these analysis models, and relative software interface is developed to enhance structural design for crafts. |
