摘　　要：针对中地球轨道(MEO)卫星微波天线连续工作时间较长带来的温度一致性问题,兼顾卫星减重的需求,文章提出了一种天线机电热一体化设计方法。从分析MEO热环境出发,筛选出极端低、高温工况,采用纳米膜、高导热石墨板和分布式测控温系统相结合的手段,提出了一种新的天线热控方法,节省了传统的有源安装板,优化了2/3的测控温线缆。经过有限元仿真和模块级试验,验证了该方法的有效性,试验结果表明:该机电热一体化设计方法能够满足温度一致性要求,对短时高热耗的天线热控具有重要的借鉴意义。In response to the temperature consistency problem caused by long continuous working time of microwave antenna for medium earth orbit(MEO)satellite,and considering the need for satellite weight reduction,an integrated design method of mechanical-electrical-thermal for antenna is proposed in this paper.Starting from the analysis of MEO thermal environment,extreme low and high temperature conditions are selected,and an innovative antenna thermal control method is proposed by combining nanofilm,high thermal conductivity graphite,and distributed temperature measurement and control system.This method saves traditional active installation plate and optimize 2/3 cables,the effectiveness of this method has been verified through finite element simulation and module level test.The test results show that the integrated design method can meet the consistency requirements and has important reference significance for antenna thermal control with short-term and high heat consumption.
