| 摘 要： | 利用Taguchi（田口）实验方法将注塑参数设计为L9实验矩阵,在不同注塑参数下进行数值模拟,找出在模具温度、熔体温度、注射速率及保压压力等工艺参数对注塑残余应力的影响程度。结果表明：所选的工艺参数对于注塑件残余应力的影响程度不一,通过优化参数可以将注塑残余应力值降低,从而达到注塑产品质量的提高。

| Abstract: | L9 experimental matrix based on injection parameters was used.Numerical simulation was carried out by different injection parameters.And the influence degree on the value of residual stress was found out by the selected injection parameters,such as the mould temperature,melt temperature,injection rate and packing pressure.The result showed that the selected injection parameters have different extent of effects on the residual stress in plastic product;the residual stress can be decreased by using the optimal parameters so that the quality of the plastic products can be improved. |
