摘要: 针对测试性验证试验中部分故障模式不可注入,或注入后易导致装备出现不可修复的损坏等问题,提出了基于“故障模式-功能-状态”(FFS)故障行为模型的等效故障注入方法。首先,对FFS总体建模思路进行了描述,提出将“功能”作为基本建模要素,在分析装备自身多元建模信息的基础上,建立了故障行为模型。其次,对各相关矩阵和行为状态向量进行了定义,研究了故障模式、功能、状态间的不确定信息表征方法,提出了故障模式-状态相关矩阵的求解方法。最后,给出了等效故障模式的定义和基于FFS故障行为模型的等效故障注入流程。将所提方法应用于某装备发射控制系统,结果表明,所提方法能够实现等效故障注入,故障注入率提高约16.7%。

Abstract: A equivalent fault injection method based on failure mode-function-state (FFS) failure behavior model is proposed to deal with the incapability of fault injection and permanent damage caused by fault injection in the fault injection based testability verification test. Firstly, the general FFS modeling idea is described, and the function is proposed as the basic element of modeling. Based on the multivariate modeling information of equipment, the failure behavior model is established. Then, the correlation matrixes and behavior state vector are defined, the method for characterizing uncertain information among failure modes, functions, and states is studied, and the calculation method for fault mode-state correlation matrix is proposed. Finally, the definition of equivalent failure mode and the equivalent fault injection process based on FFS failure behavior model are proposed. This method was applied to a launch control system. The results show that by this method the equivalent fault injection can be realized, and the rate of fault injection is increased by about 16.7%.

Key words: testability verification test, equivalent fault, multiple information, failure behavior model, behavior characteristic
