    Abstract:

    The development about experiment of vibration and response for rotating blade with dry friction damper was summarized. Device , excitation method and dynamic characteristic method used in vibration test for rotating blade with dry friction damper were discussed emphatically , in order to provide technical support for test program, Improving structural reliability and efficiency, vibration reduction and lifetime extension. Experiment of vibration and response for rotating blade with dry friction damper were divided into two types:dynamic characteristic test based on loading the centrifugal force on the blade and damper, vibration stress measure based on blade and damper actuated by engine.According to present situation of experiment of vibration and response for rotating blade with dry friction damper,new research directions were suggested:establishment of test equipment model library,which according to the different tenon structure and angle of adjacent blade; exploring the coupling loading method for high frequency and measuring method of vibration response; investigation on excitation method more in line with real environment, developing the high idetifying measure method using the strain gauge and sensor.
