Abstract:

Based on the composite wing of certain Unmanned Aerial Vehicle (UAV),four different finite element models of the composite wing are established by MCSPatranUsing those four finite element models,strength check and modal analysis are carried out with the finite element software MSCNastranAccording to the analysis results of the loadings of components,the structural form and material of the composite wing are optimizedThe service life is prolonged and the production cost is reduced for the Unmanned Aerial Vehicle by the optimization analysis
