An Overall Evaluation Method for Mold Design Schemes of Complex Cavity Based on the Extension Methodology
-
摘要: 针对设计方案评审过程中存在着交错耦合关系如何确立等问题,运用可拓学理论,通过对模具设计方案物元模型、关联函数、权重和隶属度等关联关系的研究,构建了基于可拓理论复杂型腔模具设计方案综合评价模型。并通过设计实例,从成型工艺、模具结构、模具材料、模具成本等4个方面对其设计方案进行了综合评价。评价实例证明了该评价方法具有操作简单、实用性强等特点。Abstract: Aiming to establish crisscross-coupling relationship in the design evaluation process, an overall evaluation model for complex cavity mold design schemes via the extension methodology is proposed based on the matterelement model, correlation function, weight and membership.A mold for design scheme is discussed, in which isbased on the forming technology, mold structure, mold material and manufacture cost.The result in practice showsthat the method on the extension theory is simple, effective.
