摘 要:采用ActiveX技术,实现了VB对Moldflow内部对象的控制,开发出了材料分析辅助系统,此系统具有对给定的模型进行多种材料连续自动分析的功能。并通过质量指标权重的设置,构建了基于材料综合质量指标值优化排序的加权评价方法,从而帮助了设计者选择最合适的塑料材料。实例计算表明,使用本系统不但解决了Moldflow无法对多种材料进行连续分析的难题,而且还有助于塑件材料的优化选择,提高了产品质量和设计效率,降低了生产成本。

Abstract: The VB controlled objects of Moldflow by ActiveX technology was realized. The aided decision system of materials analysis was designed. The system could conduct automatic and consecutive analyses towards the specified materials, setting weight values, and a weight evaluation method base on integration performance index of materials was established. Hence, it provides assistance to the designers in selecting proper part materials. The case study results demonstrate that, the system improves the limitations of Moldflow in the simulation process, such as lack of analysis assisting the selection of appropriate materials for the designers, and that can improve the quality of parts, advance efficiency, decrease cost.
Key words: Moldflow; materials analysis; design optimization; decision system; moldflow plastics insight (MPI)
