Abstract

Abstract: Presenting a fault diagnosis method in complex machine based on the shearer virtual prototyp experiment.The method is building a series of fault virtual prototyp experiment for its weight of testpoint,and then acquiring the fault-expression-vector corresponds to weight information by wavelet decomposition and neural network analysis.Through the analysis of neural network,building a classification system to diagnose the fault of machine.The fault virtual prototyp was applied to whole machine,and various testpoint was set.At length,the method was verified by simulation signals and engineering examples of mechanical fault diagnosis effectively.

Key words: fault diagnosis, flexible bodies, virtual prototype, neural network
