摘要: 现有测试性建模方法有一定的约束条件,包括故障判据的一致性、故障传递关系的一致性、测试的逻辑值判据一致性.针对通断式多态系统具有的状态差异性的特点,提出了一种扩展测试性建模方法.在引入状态集合的基础上,对故障、测试、 D 矩阵和诊断树进行了扩展定义,最后定义了扩展测试性模型.介绍了扩展测试性建模分析的算法,主要有模型建立算法、扩展 D 矩阵生成算法、扩展诊断树生成算法.以某液压操纵系统为例进行了应用,结果验证了方法的可行性和有效性.Abstract: The existing methods for testability-modeling have some constraints, including the consistency of failure criterion, failure transmitting and logical-value criterion of test. Aiming at states differences of on-off multi-state system, the method of extended testability modeling was proposed. Failure, test, D matrix and diagnostic tree were defined extended with the introduction of states, and an extended testability model was defined also. The algorithms for extended testability modeling and analysis were described, which include modeling, generations of extended D matrix and extended diagnostic tree. A hydraulic control system was taken as an example for the engineering application, which shows that this method is feasible and effective.
