| description | The invention discloses a structure optimization design method for improving the inherent frequency of a large-aperture antenna system. The method comprises the steps of antenna structure state evaluation, conceptual design of an improved structure, detailed design of the improved structure and the like. According to the method, the parameter optimization model is created and the parameter optimization calculation is performed based on the structural material distribution obtained through topological optimization calculation, so that the antenna structure more conforming to the engineering practice is obtained, and the method is suitable for the fields of structural optimization design with sensitive contrast stiffness or structural optimization design of a large-aperture antenna system with improvement of the inherent frequency as the target and the like.
本发明公开了一种提升大口径天线系统固有频率的结构优化设计方法。该方法包括天线结构状态评估、改进结构的概念设计、改进结构的详细设计等步骤。本发明基于拓扑优化计算得到的结构材料分布，创建参数优化模型并进行参数优化计算，从而得到更符合工程实际的天线结构，适用于对比刚度敏感的结构优化设计或以提升固有频率为目标的大口径 |
