This paper proposes a method of fault position detection and location for the axle of railway vehicles, which based on Acoustic Emission technique. The method is used to denoise the Acoustic Emission signal by wavelet transformation and makes signal of continuous processing by Butterworth filter; then finds the maximum in reverse direction after taking threshold comparison with continuous signal in order to form the point of the first peak. Finally fault location is on the basis of the time from the first peak to the sensor. The experimental results indicate that the method can remove interference effectively and its positioning accuracy is better than the location method of Gabor transformation. After all, this method has a great value in engineering application.
