摘要
能量设计因子作为产品设计信息与能量特性的联系桥梁,一般与众多设计元素存在耦合关系,难以直接转换成设计过程需要的设计参数或控制措施,针对此问题,建立了能量设计因子耦合分解机制。耦合分解机制的主体由耦合性质分析、耦合元素关系矩阵构造、耦合元素设计优先级评定、能量设计参数与取值建议(或控制措施与控制目标)获取四个核心环节构成。以数控机床的耦合能量设计因子极限切削宽度bDlim为例,对耦合分解机制进行了说明。
The EDF connecting the product's design information and its energy characteristics was difficult to convert to design parameters and control measures, which was coupled with large amount of design elements. Aiming to solve this problem, the decoupling mechanism of EDF was built. The deeoupling mechanism was constituted by analyzing coupling characteristics, constructing coupling ele- ment relation matrix(CERM) ,evaluating design priority of coupled element and gaining energy design parameters and optimum value(or control measures and target). In addition,the max cut width bDum of NC machines was selected as an illustrative example to show the decoupling mechanism of EDF.
