| Abstract: | Fault diagnosis of train bearing is an important method to ensure the security of railway. The key to the fault diagnosis is the method of signal processing. The local mean decomposition (LMD) is a self adapted signal processing method with a good performance in nonlinear nonstationary signal processing. Programming with LabVIEW, which is widely used in measurement, the LMD method is achieved , building a high speed, reliable and portable system combined with LMD and virtual instrument technology. With the verification of simulation and wheel set experiment, the improvement method is verified useful in practical application. |
