【摘要】 机翼共形承载天线受到复杂服役环境((气动力载载、热载载、))响产生结构变形形,导致天线电性能恶化。因此,精确设计共形天线的构变并进行实时形形重变成为保障天线性能稳定准确的关键问题。本研究使用模态法,基于微带天线模型设计了2×8的16元矩形面天线阵,在此基础上搭建了共形天线载、模拟平台,构合静态电阻应形仪与3D摄响测量系统,采集应形数据与真实形形,通过有限元模态分析,建立模态-应形映射模型,实现形形重变。实验构果表明,在4种载、工况下,形形重变效果较好,验证了重变方法在形形场景下的准确性,为共形天线的形性协同调控提供了理论与技术支撑。更多还原

【Abstract】 Wing-conformal load-bearing antennas are prone to structural deformation under complex service environments(e.g.,aerodynamic loads,thermal loads),leading to the degradation of electromagnetic performance.Accurate structural design and real-time deformation reconstruction of conformal antennas are therefore critical to ensuring stable and reliable antenna performance.In this study,a modal-based deformation reconstruction method is employed.A 2×8 16-element rectangular planar microstrip antenna array is designed,and a conformal antenna load simulation platform is developed.By integrating a static resistance strain gauge and a 3D photogrammetric system,strain data and actual deformation fields are synchronously acquired.A modal-strain mapping model is established based on finite element modal analysis to achieve deformation reconstruction.Experimental results demonstrate favorable deformation reconstruction performance under four typical load conditions,verifying the accuracy of the proposed method in complex deformation scenarios.This work provides theoretical and technical support for the synergistic regulation of conformal antenna performance and structural integrity.更多还原
