摘要: 提出面向对象的计算机辅助故障模式影响分析(CFMEA)方法,建立了控制系统仿真模板,将其数据、操作和性能封装成一个对象,对象间通过属性进行因果推理,实现FMEA向故障树(FTA)的自动转换.引入控制系统性能可靠性概念,建立控制系统性能和功能综合可靠性模型,开发相应的解算方法.实例分析证明了基于仿真模板的控制系统可靠性分析的有效性, 综合了功能和性能可靠性分析的优点.

Abstract: An object-oriented method of computer aided failure mode and effect analysis (CFMEA) was presented. The simulation modular of control system was established, in which the data, performance and mapping relation were encapsulated in component model and typical control modular. Through causal reasoning at attribution between objects, it is easy to transfer the CFMEA results into corresponding fault tree so as to realize the reliability analysis for control system. In the control system modeling, the dynamic performance in reliability model was inducted, its solution method based on simulation was provided. The application results indicate that the reliability analysis based on simulation modular is effective and easy to combine the advantage of system function and performance.
