摘要
以汽车轮眉为研究对象,选取模具温度、熔体温度、保压压力以及保压时间4个工艺参数作为实验变量,以轮眉的最小翘曲变形作为优化目标,基于响应面法的中心复合设计方法,结合CAE仿真模拟技术,建立了轮眉翘曲变形同工艺参数之间的响应模型,通过方差分析研究了工艺参数及其交互作用对优化目标的影响。通过软件优化确定了最优工艺参数组合,实验结果表明最大翘曲变形量从6.311 mm降至3.367 mm。
Taking car wheel trims as research object, mold temperature, melt temperature, packing pressure and packing time were selected as the experimental variable, with the warpage deformation as the optimization goals. The response surface model which described the relationship between warpage deformation and processing parameters were established by using central composite design （CCD） of experiments and CAE simulation technique. Also the interactions of process parameter on the optimization target was analysed by ANOVA. Finally, optimal sequence were obtained by using design-expert. Experiments showed that the amount of warpage of plastic parts was reduced from 6. 311 to 3. 367 mm.
