What is the rapid monitoring device and method for wheel tread abrasion of high-speed railway?
Latest company news about What is the rapid monitoring device and method for wheel tread abrasion of high-speed railway?

The company has developed a rapid monitoring device and method for wheel tread scratches on high-speed railways, including a wheelset axle box, an acceleration sensor, a data acquisition unit, and a data processing unit. An acceleration sensor is installed vertically on the wheelset axle box for obtaining The vertical vibration acceleration of the wheel-set axle box; the data acquisition unit continuously collects the vertical vibration acceleration data of the axle box and stores it in segments; the data processing unit uses the characteristics of multi-frequency vibration caused by the impact to identify the scratch fault and the scratch depth The data processing unit reads the vibration acceleration data segment by segment, and then uses the improved empirical mode decomposition method to quickly process the vibration acceleration data, extracts the vibration acceleration waveforms of different frequencies, and analyzes the vibration acceleration waveforms of each frequency. The envelope is demodulated, and FFT analysis is performed to extract the number of shocks per unit time of the shock resonance wave of each frequency.
