旋转机械碰摩故障的BP神经网诊断

THE DIAGNOSIS OF RUBBING FAULT IN ROTATING MACHINERY WITH BP NEURAL NETWORK

本文介绍了旋转机械碰摩故障的ＢＰ神经网络诊断方法，并利用一种新的转子碰摩故障模拟试验系统，验证了方法的可行性。本方法既能诊断碰摩故障的发生，又能判定碰摩程度。

A diagnostic method of rubbing fault in rotating machinery with BP neural network is introduced in the paper. Its feasibility is testified by using a new kind of simulating test system. The rubbing fault can be detected and its intensity can be estimated by the method offered.
