摘　　要：以某汽车大型塑料件为例,以体积收缩率变化及翘曲量为质量指标,结合Taguchi DOE及Moldflow数值模拟技术,研究相关工艺参数对质量指标的影响,并得到了各工艺参数水平的最优组合。经公式预测及Moldflow数值模拟验证,工艺参数的优化组合使体积收缩率变化和翘曲量达到试验范围内最小。Taking a large-scale automotive plastic part as an example, Taguchi DOE and Moldflow numerical simulation technology were conducted to study the influence of process parameters on volume shrinkage variation and warpage, which were regarded as quality indicators.Moreover, an optimal set of the parameters was obtained based on different levels.As formula predicted and numerical simulation proved, the optimal set of the parameters made volume shrinkage variation and warpage minimum during experimental range.
