摘　　要：针对某30%短玻纤增强聚丙烯材料的鼓风机叶轮,基于计算机模拟技术与正交试验法探究其优化方案。结果表明:各工艺参数对鼓风机叶轮圆柱度的影响程度排序为:保压时间>熔体温度>模具温度>冷却时间>保压压力;对叶轮熔接线状态的影响程度排序为:冷却时间>保压压力>熔体温度>模具温度>保压时间,综合分析最优工艺参数组合为A1B1C2D2E4。依据最优工艺参数进行仿真模拟,圆柱度及熔接线状态与初始工艺相比,提高60.0%和36.2%,满足鼓风机叶轮的设计要求,并得到试模验证。For a blower impeller with 30% short glass fiber reinforced polypropylene material, the optimization scheme was explored based on computer simulation technology and orthogonal test method. The results show that the order of influence degree of each process parameter on the cylindricity of blower impeller is as follows: holding time>melt temperature>mold temperature>cooling time>holding pressure. The order of the influence degree on the state of impeller welding line is: cooling time>holding pressure>melt temperature>mold temperature>holding time. The optimal combination of process parameters is A-1B1C2D2E4. The simulation was carried out according to the optimal process parameters. Compared with the initial process, the cylindricity and the welding line state were increased by 60.0% and36.2%, which met the design requirements of the blower impeller and were verified by the test model.
