【Abstract】 An approach of gear fault classification,combing higher-order statistics with radial basis function (RBF) networks,is proposed. Higher-order statistics can eliminate additive Gaussian measurement noise, boost signal-to-noise ratio. The radial basis function (RBF) network, as an alternative to the BP network, preserves several advantages, such as fast convergence and best approximation to non-linear functions, etc. In this paper, the higher-order statistics calculated from vibration signals of a gearbox are used as input features, and an RBF network as the classifier, gear faults are successfully recognized. The experimental results show that the method of fault classification combining higher-order statistics with RBF network is very effective.更多还原
