摘要
The method involves actuating single blades by an impulse one after the other in a condition decoupled from the remaining blades. The non tested blades that are attached to the blades temporarily are adjusted additionally by an identical additional weight (7), such that the coupling effects caused by these adjusted blades and interfering the measuring of the oscillating response of the tested blade are displaced from the resonant frequency vicinity and thus are eliminated.
