摘要：

针对复杂装备设计研制阶段的现场可更换单元(line replaceable unit, LRU)规划问题, 以功能-行为-结构(function behavior structure, FBS)和可靠性、维修性、保障性、测试性(reliability maintainability supportability testability, RMST)作为LRU规划的影响因素, 提出了一种基于性能的LRU规划方法。首先, 通过建立系统的功能架构, 获取系统的零部件清单。在此基础上, 建立零部件FBS相关关系评价矩阵, 进而得到零部件综合相关矩阵, 运用模糊聚类分析实现初步的LRU规划。将RMST参量化, 建立综合评价数学模型, 对初步规划方案进行优选, 得到最佳规划方案。最后, 以某型中压整流发电机为例, 运用提出的方法实现了该装备的LRU规划, 验证了方法的有效性。

Abstract:

Aiming at the partition of line replaceable units (LRU) in design development stage of complex equipment, a LRU partition method based on performance is proposed, which function behavior structure (FBS) and reliability maintainability supportability testability (RMST) are used as the influencing factors in this method. Firstly, the list of spare parts of system is obtained by establishing functional architecture. On this basis, the evaluation matrixes for correlation of components in FBS are established, and then a comprehensive correlation matrix of components is obtained, and the preliminary partition of LRU is finished through fuzzy cluster analysis. The comprehensive evaluation mathematical model by quantifying RMST is established to sequence the preliminary partition schemes for obtaining the optimal partition scheme. Finally, taking a certain type of medium-voltage rectifier generator as an example, the proposed method is used for LRU partition of the equipment, and the effectiveness of the method is verified.

Key words: line replaceable units (LRU) partition, fuzzy clustering, complex equipment, medium voltage rectifier generator
