摘要

摘要: 为了更好的实现加工中心的设计，减少设计过程的迭代次数，缩短开发周期，以加工中心的功能运动为核心，利用FMA结构化分解将加工中心按照"功能-运动-动作"的顺序逐层分解至相应的元动作，定义了元动作设计结构单元，在考虑各设计单元耦合性的基础上提出了FMA结构化分解驱动的加工中心设计过程规划流程；然后用可变度与敏感度双指标表示设计单元间的耦合程度，以设计结构矩阵为工具对设计单元间的耦合强度进行量化，利用基于次序指标的割裂算法对耦合强度矩阵进行割裂规划，优化设计单元的初始设计顺序，从而实现了加工中心的设计过程规划，加速了加工中心的设计与开发；最后以托盘交换架功能组元动作设计单元间的设计规划过程为例，证明了本文的可行性。

Abstract: To better realize the design of a machining center, reduce its iterative time and shorten its development cycle, the FMA (Function-Motion-Action) structural decomposition was used to decompose the machining center into its corresponding meta-action step by step according to the order of the FMA, the definitions of meta-action design structural unit were given on the basis of considering the coupling among design units, and the machining center design process planning driven by FMA structural decomposition was put forward. Then the double indexes for sensitivity and variability were introduced to express the coupling degree among design units, the design structure matrix was used to quantify the coupling strength among design units, and the tearing planning based on the index order was used to tear the coupled design units, thus the initial design sequence of design units was determined, and the machining center design process planning was implemented and can accelerate the design and development of the machining center. Finally, the automatic pallet changer of a machining center was taken as an example to prove the effectiveness of this paper.
