碳纤维复合材料天线反射面的模态分析

Modal Analysis on Antenna Reflection Surface of Carbon Fiber Compoites

从刚度设计的角度,对碳纤维复合材料(CFRP)天线反射面进行铺层设计,建立了15种纤维铺层方式的有限元模型,利用ANSYS对天线反射面进行模态分析,结果表明采用[90/45/0/-45/-A]s对称铺层的蜂窝夹层板的固有频率最大。

We conduct the lay - up design with the antenna reflection surface of Carbon Fiber Reinforced Polymer （CFRP） to meet the requirement of rigidity and 15 FEA models of fiber lay- up are constructed. We used ANSYS software to conduct the modal analysis to the antenna. The result shows that the natural frequency is the biggest when the lay- up orientation of the symmetrical comb laminate is.
