摘要
文中运用有限元分析方法,通过MSC.Patran/Nastran软件,建立了喇叭天线机架的有限元模型,分析机架结构的振动模态,计算固有频率并对结果进行综合评价。模态分析验证了机架设计的刚度和强度,为优化设计提供了参考和依据。
The finite element modal for antenna frame is established by using FEM analysis technology and the software of MSC.Patran/Nastran. The paper analyzes vibration modal of the structure, calculates the inherent frequency and evaluates the modal results. Modal analysis verifies the designed rigidity and intensity, to provide reference and basis for improving and optimizing.
