Early damage in a helicopter gearbox manifests as non-stationary disturbance signals with variable periods superimposed on vibration signals. This study constructs physically meaningful simulated data replicating early fault signals and applies wavelet transform techniques to analyze fault characteristics and occurrence timing. Implementation includes MATLAB-based signal synthesis using modulated sinusoidal functions and multi-resolution analysis via discrete wavelet transforms (DWT) with Daubechies wavelets for time-frequency localization.
