【Abstract】 A fault diagnosis method based on fuzzy neural networks is proposed for a three-axis turntable mechanical bed, The structure and learni n g algorithm of the fuzzy neural networks are presented, Also the theory of fuzzy fault diagnosis and the fault discriminance are discussed. Meanwhile a method i ntegrated vibration signals and current noise signals is applied in the fault di agnosis of the mechanical bed. Testing results show that this method is effectiv e.更多还原
