摘　　要：为提升涂布机烘箱的干燥特性,本研究针对风嘴结构及其附近区域展开研究,分析风嘴多结构参数对内部流场特性的交互影响。借助有限元分析和响应面法,建立烘箱风嘴多结构参数交互影响下的流场特性数学回归模型,基于此进行风嘴结构的优化设计,并将优化结果与仿真值进行误差比较,验证所构建回归模型的准确性。结果表明,构建的含有多结构参数的风嘴流场特性回归模型拟合度较好,基材温度、基材表面风速、基材压力3组响应值的预测值和仿真实验值误差均小于3%,能够较好描述风嘴局部流场特性变化规律。In order to improve the drying characteristics of the coating machine oven,this study was carried out on the nozzle structure and its nearby areas to analyze the interaction effect of the nozzle multi-structural parameters on the internal flow field characteristics.With the help of finite element analysis and response surface method,the mathematical regression model of flow field characteristics under the interaction of multi-structural parameters of the nozzle in the oven was established,based on which the optimization of the nozzle structure was carried out,and the optimization results were compared with the simulation values to verify the accuracy of the regression model.The results showed that the regression model of the flow field response value of the nozzle with multiple structural parameters had a good fitting degree.The error between the predicted value and the simulation experimental value of the three groups of response values of the substrate temperature,the substrate surface wind speed,and the substrate pressure were less than 3%,which could describe the change law of the local flow field characteristics of the nozzle well.
