运用md.nastran的鸟撞复合材料板显示非线性分析

摘要

For the bird strike frequently, such as the high-rise building glass, the flying plane, etc, bird and material composite plate are consiste of a simplified model by Software MSC md.patran. By setting parameters, the md. nastran analysis file is submited to, and then got in to see the result files. In the end,the deformation of material composite plate at the moment and the stress distribution of material composite plate can be seen. The stress and displacement curve of bird strike are plotted also, which provides theory basis for material composite plate structure strength design.%针对鸟撞事件的频频发生,比如高层建筑物的玻璃,空中飞行的飞机等,通过msc.md.patran软件对鸟撞复合材料板建立简化模型,并得出提交到md.nastran中分析文件.进而得到结果文件,从而查看鸟撞时各个时刻复合材料板的变形,以及查看复合材料板的应力分布.并且可以绘制出应力与位移的时间历程曲线,为复合材料板结构强度设计提供理论依据.
