Abstract：It was summarized that the principles as well as advantages and disadvantages of impulse decay method and steady state power flow method. A new mthod for estimating damping loss factor based on pulse excitation was proposed using the idea of impulse excitation and power flow. The method overcomed the defects of conventional methods.The damping loss factor of a thin steel plate was estimated using this mehtod. The results obtained by this method and Impulse decay method were compared. The result of comparison showed that more accurate damping loss factor could be obtained by the new method.
