摘要:

针对甚低频十三塔天线设计中电气与结构迭代耗时的问题,本文建立了一种甚低频十三塔天线机电耦合协同分析数学模型,依靠矩量法将天线结构信息离散化嵌入了电磁网格中,完成了结构模型和电气模型之间计算网格以及信息的传递与转换,实现了天线结构与电性能的协同分析。所提方法跨越了异构系统之间网格模型的单元形状不匹配的问题,在结构参数修改后,即刻生成数学结构模型,转换成矩量法电气模型并计算电性能。采用机电耦合协同建模分析方法对不同恶劣工况下天线结构变形与天线电性能进行了计算,并在相同工况下与传统建模仿真计算结果进行了对比,在计算误差不超过1%的情况下计算效率提升35%,可以为恶劣工况下甚低频十三塔天线的平衡调控提供计算工具。

Abstract:

Aiming at the problem of time-consuming iterations between electrical and structural design in the very low frequency thirteen-tower antenna, a mathematical model of electromechanical coupling collaborative analysis of very low frequency thirteen-tower antenna is established. The antenna structure information is discretized and embedded into the electromagnetic grid by the method of moment. The calculation grid between the structural model and the electrical model and the transmission and conversion of information are completed, and the collaborative analysis of antenna structure and electrical performance is realized. The proposed method overcomes the problem of unit shape mismatch of grid models between heterogeneous systems. After the structural parameters are modified, the mathematical structure model is generated immediately, which is converted into the electrical model of the moment method and the electrical performance is calculated. The electromechanical coupling collaborative modeling analysis method is used to calculate the antenna structure deformation and antenna electrical performance under different harsh conditions, and compared with the traditional modeling and simulation calculation results under the same working conditions. The calculation efficiency is improved by 35 % when the calculation error is less than 1 %, which can provide a calculation tool for the balance control of the very low frequency thirteen-tower antenna under harsh conditions.

Key words: very low frequency thirteen-tower antenna, mechanical-electric coupling, collaborative modeling, radiation resistance, effective height
