以某型无人机复合材料机翼为基础,基于MCS.Patran建立四种不同结构机翼有限元模型,并利用MCS.Nastran进行强度校核和模态分析.分析各元件的承载情况,对机翼的结构进行优化,从而提高机翼的寿命,降低生产成本.
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 resuits 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.
