  1. Then, we establish the finite element analysis models of the antenna in different structure layout, and obtain the corresponding frequencies and model shapes. finally, according to the importance of each object, we set up the model of multiple objects that aims to maximize the first natural frequency and minimize the mass. combining orthogonal experiment and variant weighting coefficient method, we formed an effective multiple objects optimized algorithm basing on the neural network and genetic algorithm

    本文首先詳細的敘述了天線結構的各組成單元,闡明了天線反射拋物面的形成原理;然後在ansys軟體環境中建立了不同結構布局下天線的有限元分析模型,分析算了各種情況下天線的的固有與振型;最後依據天線各指標的重要性,建立了以一階固有最大、質量最小為目標的天線結構多目標優化設模型,並基於神經和遺傳演算法,結合正交實驗和變加系數技術,形成了一種有效的多目標優化演算法,在matlab平臺下實現了天線的結構多目標優化設算程序,求得了天線的最佳結構參數。
