摘要:
故障树分析( Fault Tree Analysis) 在系统可靠性评估中起着至关重要的作用。 然而,作为故障树分析的核心故障树(FT)的构建,传统构建故障树的方法存在耗时长且容易出错等缺点。 为了解决这些问题并应对复杂系统自动建造故障树的困难,该文提出一种基于元部件模型及系统结构模型的规范化描述方法,并以此为基础,通过建立元部件模型库、复杂标识符库,设计出故障树自动建树及分析软件,实现系统结构模型搭建、自动建树、复杂结构识别处理及可靠性分析过程的全自动化。 详细阐述了故障树自动建树软件自动建树及分析的基本步骤,并通过一个简化的汽车 ABS 系统应用实例验证了该软件的有效性和可行性。 实例应用结果表明,该故障树自动建树及分析软件不仅能够实现自动构建和分析故障树,提高工作效率,而且能够识别处理具有复杂结构的故障树,对复杂系统的自动建树及可靠性分析的推广具有重要意义。
Abstract:
Fault tree analysis plays a crucial role in system reliability assessment. However,as the core fault tree ( FT) construction offault tree analysis,the traditional method of constru－cting fault tree has the disadvantages of time-consuming and error-prone problems. Inorder to solve these problems and cope with the difficulty of automatically building fault trees in complex systems, we propose astandardized description method based on meta-component model and system structure model,and takes this as the foundation. By establishing meta-component model library and complex identifier library,the fault tree automatic tree construction and analysis software is designed to realize system structure model construction, automatic tree building, full automation of complex structure identification andreliability analysis processes. We provide a detailed explanation of the basic steps for automatic tree building and analysis of fault treesoftware,and verify the effectiveness and feasibility of the software through a simplified application example of automotive ABS system.The application results show that the fault tree automatic tree construction and analysis software can not only automatically build andanalyze fault trees,improve work efficiency,but also identify and process fault trees with complex structures,which is of great significanceto the promotion of automatic tree building and reliability analysis of complex systems.
