摘　　要：针对反射面天线风荷与结构参数具有随机性的特点,提出了随机因素下机电集成设计方法。首先,导出了随机因素下反射面天线电磁场与位移场的场耦合关系式。其次,提出了基于新关系式的机电集成稳健优化设计模型,给出了求解的策略与方法。最后,将所提出的理论与方法应用于某8m与40m天线中,得到了满意的结果。Considering the probabilistic properties of wind load and structural parameters, a kind of mechanical and electromagnetic integrated optimization design method is proposed in this paper. To begin with, a new field coupling relationship between structural displacement and electromagnetic field is deduced when consid- ering the random factors. Then the synthetic optimization model and solving strategy are given. Finally the proposed theory and method are applied to both antennas with the diameters of 8 and 40 meters, and good results aregotten.
