基于FMA分解的关键质量特性映射变换技术
|
摘要
在对数控机床进行FMA结构化分解的基础上,采用决策试验与实验评估法(DEMATEL,decision making trial and evaluation laboratory)对主运动之间关系进行了耦合解耦分析,得到部件主运动性能耦合矩阵。引入了一种间接映射来代替主运动之间的同代耦合关系对二级运动层的影响,分别采用信息耦合度、耦合可变度来度量这种间接映射和直接映射关系,并利用模糊层次分析法(FAHP,fuzzy analytic hierarchy process)对映射关系进行了量化,从而建立了主运动-二级运动性能之间的映射变换矩阵;结合部件主运动性能耦合矩阵,完成了关键质量特性在功能-运动层的传递,并通过实例对比证明了该映射方法的有效性和合理性。
Based on the FMA structure decomposition of NC machine tool,the coupling and decoupling analysis of the relationships between the main motions were carried out by using the decision making trial and evaluation laboratory(DEMATEL),and the performance coupling matrix of main motions of components was obtained.An indirect mapping relation was introduced to replace the influence of the same generation coupling of main motions on the secondary motion layer;the information coupling degree and coupling variable degree were used to measure the indirect mapping and the direct mapping relationships respectively,and the fuzzy analytic hierarchy process(FAHP)was used to quantify them,thus estalishing the mapping transformation matrix between the main motions and the secondary motions performance,which in combination with the performance coupling matrix of main motions of components,completed thetransfer of key quality characteristics in the function-motion layer.The validity and rationality of the mapping method are proved by the comparison of examples.
