基于贝叶斯网络的机械设备故障诊断方法研究

Research on the mechanism fault diagnosis method based on Bayesian networks

建立了一种基于贝叶斯网络的机械设备故障诊断模型,引入评分函数和蚁群算法对模型进行了优化,在模型建立过程中引入知识进行自我学习,减少了因检测对象造成的不确定信息,提高了机械设备故障检测的可信度,最后通过实例进行了验证。

It establishes a model of mechanical equipment fault diagnosis based on Bayesian network. Based on the score function and ant colony algorithm it optimizes the model. Appling adopting self-learning in the process of building model,this model reduces the uncertainty caused by the detection object,and improves the reliability of mechanical equipment fault detection. An example shows that the model is effective.
