　　The fast Fourier transform (FFT) algorithm is commonly used to derive the power density spectrum of scattered point data in the frequency domain.In the present paper, the standard fast Fourier transform is used to investigate the natural frequencies of nonlinear free transverse vibration of axially moving beams.
