摘　　要：航空发动机压气机低速模拟实验台所用树脂叶片注塑成型过程复杂,叶片成型精度由模腔和工艺参数决定。为探索工艺参数及其交互作用对叶片成型精度的影响规律,提出并研究了压气机叶片注塑变形主工艺因素的二次分析方法。首先基于析因试验研究了熔体温度、模具温度等工艺参数对叶片成型变形的影响,揭示了对叶片变形影响显著的工艺参数及其交互作用;再基于响应面方法分析了各主工艺参数及其交互作用对叶片变形的影响规律。仿真试验结果表明,保压时间、熔体温度与保压时间的交互作用等是影响叶片变形的显著因素。Resign blade used in low speed research compressor of aeroengine injection molding process is complex.The precision of blade forming is determined by the cavity and technological parameters.In order to explore the influenceof technological parameters and their interaction on blade forming precision.Twice-analysis method of the main technologicalparameters of the compressor blade injection molding is studied in this paper.Firstly,the influence of technologicalparameters such as melt temperature,mold temperature on blade deformation is studied based on factorial experiment.Then,the influence rule of the main process parameters and their interaction on blade deformation is revealed based on theresponse surface method.The results of simulation experiments show that packing time,the interaction of packing time andmelt temperature are the significant factors to blade deformation.
