| Abstract: | According to the vibration produced by the scratch on the wheel tread during running on rails an acceleration sensor is used to detect the scratch. A DSP sampling technique is used for the data acquisition. A concept of wavelet packet energy feature is proposed for the detection of the scratch on the wheel tread. |
