According to conventional Fast Fourier Transform(FFT) algorithm not fit to analyze train vibration spectrum due to its leakage and picket fence effects, which could not detect train vibration acceleration accurately, an improved algorithm based on three spectral lines was presented using window functions and interpolation algorithms to correct the measurement. The simulation results had verified the effectiveness and practicability of the algorithm.
