| Abstract: | Frequency/wave number spectra are given using the fast Fourier transform and maximum entropy spectral analysis. Excitation responses of the middle and tail parts of the torpedo shell are analyzed by the frequency/wave number spectrum method. Wave numbers, wave velocity, types and directions of wave propagation in the shell are obtained and discussed. |

| Keywords: | vibration wave propagation frequency/wave number spectrum |
