摘　　要：利用Taguchi试验设计法,以大型平板电视机面板为研究对象,把注塑过程中的熔体温度、模具温度等6个工艺参数作为翘曲的影响因素,设计了正交试验矩阵,对各工艺组合进行了CAE仿真试验。以减小塑件翘曲为目标,利用信噪比来衡量塑件的品质水平,通过计算分析各工艺参数的信噪比,获得了最优工艺参数组合。通过变异数分析(ANONA)技术分析了各工艺参数对塑件翘曲的影响,得到了各工艺参数的影响因子,并对最优工艺参数组合进行了验证。The optimization method of Taguchi experimental design was used to optimize the processing parameters in order to minimize the warpage of the front panel of large LCD TV. Considering the injection processing parameters such as melt temperature, mold temperature, packing pressure, packing time,injection time, cooling time, a series of CAE simulation experiments were proceeded to exploit the warpage. The signal to noise ratio S/N was utilized to find out the optimum factor levels and the relative significance of each processing parameters on warpage was also acquired based on the standard ANOVA. Confirmation analysis test with the optimal levels of the processing parameters was also carried out.
