基于MSC Nastran的机身壁板剪切试验件屈曲分析

Buckling analysis on shear test specimen of fuselage panel based on MSC Nastran

对机身壁板剪切稳定性试验件进行初步强度分析,利用MSC Nastran的屈曲求解器对试验件进行屈曲载荷的计算,将计算出的屈曲载荷施加在试验件上,然后用MSC Nastran的静力求解器分析试验件应力,得出试验件考核部位的应力云图,为后续试验设计提供参考.

The strength of shear test specimen of fuselage panel is analyzed. The buckling load on test specimen is calculated by the buckling solver of MSC Nastran, which is loaded on the test specimen. Then the stress on the test specimen is analyzed by the statics solver of MSC Nastran and the stress contour of key part of the specimen is obtained, which can provide reference for the following test design.
