Quantitative Measurement of Vibration Localization of Blisk with Damping Coating Based on Experimental Mode

Vibration control of blisk by attaching damping coating is a new technique. To implement this technology effectively， it is necessary to measure the degree of vibration localization of blisk for different coating schemes. Based on experimental modal data， a quantitative measurement method for the vibration localization of blisk is proposed. Firstly， the theory of quantitative measurement of the degree of vibration localization was proposed， and the reasonability was verified. Then， the procedure of quantitative measurement of vibration localization of blisk with damping coating was presented. Lastly， the vibration localizations of blisk with three coating schemes were tested. The results showed that the developed method can effectively measure the vibration localization of blisk with different coating schemes and the degree of vibration localization of blisk becomes more evident and fluctuates with the increase of coating area.
