事故树与人工神经网络在提升机故障预测中的应用

The application of accidental tree and artificial neural networks in hoist fault prediction

研究了制动系统失效的故障机理，并建立了制动系统失效的事故树及相应的人工神经网络结构。用Ｆｕｓｓｅｌｌ－Ｖｅｓｅｌｙ算法求出了事故树的最小割集并抽取出相应的规则。分别利用最小割集抽取的规则和人工神经网络的联想记忆功能，进行故障的预测预报。

The paper studies the fault mechanism of braking system fail and buildsthe accidental tree and artificial neural network(ANN) model. Based onFussed-Vesely algebre, the smallest-sets and the rules are obtained.Moreover according to the rules and remembering functions of ANN, therunning state of braking systems can be predicted.
