New Method for Spectrum Correction of Damped Free Vibration Response

摘要：

This paper presents a spectrum correction method based on complex analytic band-pass filter. This method can improve the precision of spectrum correction of damped free vibration response, and reduce the spectral leakage of negative frequency component caused by FFT. Results of simulations and testing show that the precision of spectrum correction can be rather high when the natural frequency of each modal parameter is far from the others.
