摘　　要：基于Moldflow软件对某笔记本电脑显示器外壳进行系统创建及模拟分析,采用Plackett-Burman方法筛选实验设计,对熔体温度、模具温度、压缩力、压缩速度、压缩距离和压缩时间6因子进行筛选,以最大翘曲变形量、平均熔接线和平均体积收缩率为目标,找出显著影响因子,并对显著影响因子进行响应曲面优化分析。通过模拟验证得出最佳工艺参数组合:模具温度78.4090℃,压缩力为56.7837 t,压缩时间为13.3636 s。A system was created and simulated for the laptop monitor casing based on Moldflow.The Plackett-Burman method was used to screen the experimental design for six factors:melt temperature,mold temperature,compression force,compression speed,compression distance,and compression time.The maximum warping deformation,average fusion line,and average volume shrinkage were selected as the targets to identify significant influencing factors.Response curve optimization analysis was conducted on the factors,and the optimal process parameter combination was finally obtained through simulation verification as follows:mold temperature is 78.4090℃,compression force is 56.7837 t,and compression time is 13.3636 s.
