摘要
对某型直升机蜂窝夹层结构抗弯刚度进行了深入探讨,给出理论上分析计算蜂窝夹层结构抗弯刚度的一般方法,得出了影响弯曲刚度的主要因素。并通过有限元分析软件Nastran对一典型蜂窝夹层结构抗弯刚度进行有限元分析,得出了正确的蜂窝夹层结构应力云图和变形,具有一定的工程指导意义。
According to the flexural rigidity of helicopter＇s honeycomb sandwich composite, it＇s flexural rigidity calculation way is discussed, the main factor of this result is got. The honeycomb sandwich composite stress distribution and deformation with the FEA element software Nastran are calculated, the result of the honeycomb sandwich composite＇s stress distribution and deformation is also got, all these are useful to the engineering.
