摘要: 吸波涂层的喷涂厚度对共形天线吸波性能有直接影响。基于正交实验设计方法设计25组不 同的喷涂工艺参数水平组合,并完成吸波涂层喷涂实验,获取相应的吸波涂层厚度数据。对吸波涂层厚度数据进行极差分析、方差分析和非线性回归分析,建立吸波涂层厚度预测回归模型。结果表明:喷涂工艺参数对吸波涂层厚度的影响按由大到小次序排序,依次为喷涂速度>步进距离>喷涂距离>涂料黏度>喷涂角度>喷枪气压;喷涂速度对吸波涂层厚度具有显著影响;吸波涂层厚度预测回归模型可准确表征吸波涂层厚度与喷涂速度、涂料黏度、喷涂距离和步进距离4个喷涂工艺参数间的定量关系。

Abstract: The wave-absorbing coating thickness has direct effect on the wave-absorbing performance of conformal antenna. 25 groups of spraying process parameter level combinations were designed using the orthogonal experimental design method. The corresponding wave-absorbing coating thickness data were obtained through 25 sets of wave-absorbing coating spraying experiments. The range analysis,variance analysis and nonlinear regression analysis were made for the thickness data of wave-absorbing coating. The result shows that the influences of spraying process parameters on the thickness of wave-absorbing coating are sorted in descending order:spraying speed> stepping distance> spraying distance> paint viscosity> spraying angle> spray gun air pressure. The spraying speed has a significant effect on the thickness of wave-absorbing coating. A regression model for predicting the thickness of wave-absorbing coating was established. It can accurately characterize the quantitative relationship among the wave-absorbing coating thickness and the spraying process parameters.
