摘要
本文主要研究天线结构形状优化设计的数学模型问题。首先建立了一般结构单工况及多工况的优化设计模型，其次提出了天线结构在自重、风荷作用下受精度、应力和稳定性约束的多工况优化设计的数学模型，并根据选材的特点将设计变量取为离散变量，对以上模型进行了近似处理[7]，建立了符合工程结构的天线结构多工况离散变量优化设计的数学模型。算例结果表明此模型可以用于实际的天线结构设计中。
This paper mainly discusses antenna structure's optimum design. First, ordinary optimum design model under single and multiple loading conditions is presented. Second, the model of antenna structure under multiple loading condition, which is constrained by antenna structure's accuracy, stress and stability under the self -gravity and wind loading, is given- Based on the characteristics of different materials, the design variables are used as discrete variables. Being treated with approximation concepts, the model applicable to general engineering,which accords with discrete variables optimum design, is set up. Example shows that the model may use for designing practical antenna structure.
