Исследование вибрационной нагруженности лопаток компрессоров при касании о прирабатываемое покрытие

Abstract

The work present results of rotor blades vibrational loading experimental studies of advanced engines compressors at the touch of the abradable coating. It has been shown that in certain cases the individual blades experience strong vibrational excitation of touching them abradable coating, wherein the time amplitude of the vibration stress can increase. Has been studied mechanisms of blade vibrations detected diagnostic features touching the blades of the abradable coating and offered recommendations to ensure the strength of the vibration vane compressors during bench testing.
