三维中空复合材料天线罩的有限元结构分析
|
摘要
某类型天线罩外形尺寸较大,减重要求高,三维中空复合材料可满足该类型天线罩透波和结构高强的要求。针对上述使用要求和实际工况,选择三维中空织物复合材料为主体结构,玻璃纤维增强环氧树脂复合材料为补强面层,制备三维中空结构天线罩,采用有限元分析软件建立三维中空结构天线罩的有限元模型,对该类型天线罩在使用工况下的刚度、强度和稳定性进行分析,其计算结果满足刚度、强度和稳定性的要求,并通过压力试验验证中空夹层天线罩的变形量与有限元分析结果保持一致,从而指导该天线罩的铺层设计、优化及材料的选用。
The radome requires large external dimensions and the weight saving. The hollow sandwich composite material can meet the requirements of transmitting wave and light high-strength. Based on the above requirement and actual condition,this paper puts forward the choice of glass fiber reinforced epoxy resin composite material for skin,and three-dimensional hollow fabric composite material for the core material of A sandwich structure radome. This article uses finite element analysis software to establish the three-dimensional finite element model of hollow sandwich radome,and the radome stiffness,strength and stability under the operating conditions are analyzed. The calculation results meet the requirements of stiffness,strength and stability. And,the pressure test verifies that the deformation of hollow sandwich radome is consistent with the results of finite element analysis,which provides guidance for the layer design,material selection and optimization of the radome.
