A Rail Fault Diagnosis Method Based on Quartic C<sup>2</sup> Hermite Improved Empirical Mode Decomposition Algorithm

For compound fault detection of high-speed rail vibration signals, which presents a difficult problem, an early fault diagnosis method of an improved empirical mode decomposition (EMD) algorithm based on quartic C<sup>2</sup> Hermite interpolation is presented. First, the quartic C<su...
