| 摘 要： | 针对现有注塑过程参数优化方法存在的需要付出较高代价的问题,提出将广泛应用于电路设计优化问题的主动空间映射方法应用于注塑过程参数优化问题。针对应用过程中主动空间映射方法所无法解决的粗糙模型与精确模型在响应值空间存在较大差异的问题,提出一种改进空间映射方法,该方法引入一种新的参数提取方法,并将主动空间映射方法与输出空间映射方法相结合,一方面考虑粗糙模型与精确模型在参数空间中存在的差异,另一方面考虑粗糙模型与精确模型在响应值空间中存在的差异。针对注塑制品的尺寸指标,将本文提出的方法在Moldflow模流分析软件上进行仿真,结果证明,该方法能够利用粗糙模型结果以及少量精确模型结果获得满足设定值的注塑过程参数。

| Abstract: | Parameter setting optimization in the injection molding process was studied in this paper. Aggressive space mapping method was used to reduce time and cost of the experiment. An improved aggressive space mapping method was proposed to solve the problem when a fairly large difference of the response value space existed between the coarse model and the fine model. A new parameter extraction method was proposed. Aggressive space mapping method and output space mapping method were combined. The differences of both the parameter space and the response value space were taken into account. The proposed method was applied to the Moldflow analysis software, and the product size was used as quality index. Optimal injection molding parameters were obtained with less time and cost. |
