摘要
在直升机机体受迫振动研究中,机身模态分析是非常关键的。首先使用三维建模软件UG建立了某轻型直升机机身的三维模型,然后在Hypermesh中对直升机机身建立有限元模型,最后利用有限元分析软件ANSYS对此直升机机身进行了模态分析计算和后处理。
In the forced vibration study of helicopter fuselage, its modal analysis is very important. In this paper, fristly, the three-dimensional model of the helicopter fuselage was established by UG software. Then, the finite element model of it was set up in Hypermesh. Finally, by using finite element software ANSYS, the modal analysis of the helicopter fuselage was completed and at the same time, the postproeess of analysis data was done by the same software.
