摘要
阐述了机械设备故障诊断机理的发展,研究了一种新的状态识别方法——人工神经网络诊断法,基于并行运算的计算机新功能,是人工智能的一个重要方面,其核心思想是人脑结构的物理模拟。使用大量的专家经验对网络权值进行训练,以实现知识的存储;通过对BP算法的改进,用基因遗传工程思路指导神经网络的训练,能较好地模拟人类专家的思维过程。应用特例说明了本文所研究方法的实用性和可靠性。
In this paper we set forth the development of mechanism of mechanical equipment fauIt diagnosis,and a new condition distinguishing method Neural Net Method for fault diagnosis in mechanical equipment wasstudied.This method based on new function of computer-parallel operation, was an important part of AI(artificialintelligence).Its core thought was simulation of human brain in physics,The knowlege memory was realized bytraining the weighs of net through a huge amount of expert experience,On the basis of BP method we use GA(genetic-algorithm) method to train neural net,which can simulate better humen thought process. By practicalexemples,it may be seen that the method presented in the paper has been of practicality and reliability.
