Research on Failure Analysis Model of Complex Mechanical System

  • 摘要: 将动态故障概率与面向对象贝叶斯网络(OOBN)相结合,在系统结构功能关系和故障模式影响分析(FMEA)的基础上,建立一种适合于复杂机械系统的动态面向对象贝叶斯网络(DOOBN)故障分析模型,该方法考虑了组件故障概率随时间的变化及组件可靠性退化对系统功能状态的影响,诊断模型具有层次性、动态性,利用该模型可以方便的对复杂系统进行故障传播的分析和关联故障的定位。在ISG-发动机上的应用表明该方法既可以简化系统的故障分析模型,又使模型描述更符合系统的实时状态。
