针对现有大型客机飞行控制计算机的体系结构,运用动态故障树分析方法对系统进行可靠性分析.通过引入时间算子,为系统所包含的温贮备门事件建立了可靠性代数模型,并且在借助逻辑符号系统得到的结构函数基础上,推演出非相似余度温贮备可靠性分析的量化表达形式.这种代数模型方法可以适用于包含任何寿命分布类型部件的系统.通过对一个典型的电传飞控计算机系统进行研究,将其和经典Markov方法比较,体现出该种方法在工程中的有效性和便捷性.
Aiming at the architecture of the existing flight control computer for large passenger aircraft, the dynamic fault tree analysis method is used to analyze the reliability of the system.According to the introduction of time operator, a reliability algebra model is established for the temperature reserve events contained in the system, Logic symbol system based on the structure function, deduced non-similar redundancy temperature reserve reliability analysis of the quantitative expression.This algebraic model method can be applied to any type of life distribution of components containing the system.Through a typical telex The flight control computer system is studied and compared with the classical Markov method, which shows the effectiveness and convenience of this method in engineering.
