  • 摘要: 通过力密度迭代方法得到了索网天线的结构模型，等效地利用高斯分布模拟了制造误差和热变形误差，构建了索网天线结构误差分析的有限元模型.以制造公差和工作温度为变量，通过具体算例分析了结构误差对索网天线型面偏差的影响，并与使用蒙特卡洛法单独分析索网天线制造误差产生的型面偏差进行比较，结果表明，该方法对结构误差的分析具有准确性和可行性，可以用来评估结构误差对天线型面精度的影响.
    Abstract: The structural model of the cable antenna was obtained by the force density iterative method. The Gaussian distribution was used to simulate the manufacturing error and thermal deformation error. The finite element model of the cable network structure error analysis was constructed. Taking the manufacturing tolerance and working temperature as variables, the influence of structural error on the antenna surface deviation of the cable was analyzed by a specific example. And comparison was made with the profile deviation analyze caused by the analysis of the cable antenna manufacturing error with the Monte Carlo method.The results showed that the method had the accuracy and feasibility of structural error analysis, which could be used to evaluate the impact of the structural error to the antenna profile accuracy.
