Literature Survey of Experiment of Vibration and Response for Rotating Blade with Dry Friction Damper

Abstract

It is of important significance to study the vibration characteristics and vibration suppression technology of aero-engine rotating blades to improve the engine performance, structural integrity and working reliability. The development about experiment of vibration and response for rotating blade with dry friction damper is summarized. Device, excitation method and dynamic characteristic method used in vibration test for rotating blade with dry friction damper are discussed emphatically. Experiment of vibration and response for rotating blade with dry friction damper are divided into two types: non-rotating test and rotating test. According to present situation of experiment of vibration and response for rotating blade with dry friction damper, new research directions are suggested as follows: establishment of test equipment model library, which according to the different ten on 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 resolution measure method of vibration by using the strain gauge and sensor.
