为了研究不同因素对天线模态的影响,基于均匀试验设计理论,提出了一种索网结构模态预测的方法.该方法同时考虑多个因素对天线基频的影响,根据均匀设计表,利用回归分析法编程进行数据分析,得出各因素与基频之间的回归函数模型.利用该模型进行基频计算,所得结果与有限元软件仿真结果进行对比,结果误差不超过2%,证明该方法正确、可行.
In order to study the influence of different factors on the mode of antenna, a method of modal prediction of cable network is proposed based on uniform experimental design theory, which considers the influence of several factors on the fundamental frequency of antenna simultaneously. Based on the uniform design table, Regression analysis programming for data analysis, and draw the regression function between the various factors and the fundamental frequency model.Using the model of the fundamental frequency calculation, the results obtained and finite element software simulation results, the results of the error does not exceed 2%, that the Method is correct and feasible.
