【Abstract】 The internal mechanism of time delay filter to reduce the residual vibration of flexible structures cannotbe explained with the normal frequency characteristic.Damped frequency magnitude characteristic, introduced in this paper,shows that time delay filter can eliminate the damped sinusoid signal in certain frequencies.So,the oscillatory mode will not be activated and the residual vibration can be reduced or e- liminated.Desirable performance is obtained in the example of damped spring- mass system controlled by the time delay filter.更多还原
