| In order to carry out the research and verification of the whole engine vibration suppression technology，and to accurately an?
alyze the causes and mechanisms of vibration faults without repeatedly disassembling and assembling，a simulation tester for rub-impact
faults was designed. Detail design of the structure and key components strength verification were conducted，and the specific test steps were
described. The high speed stator-rotor rub-impact faults were simulated using the radial and axial automatic feed rub-impact module and
the automatic lateral displacement module installed on the split case. Various typical rub-impact faults of the engine and the rub-impact
conditions between different materials were simulated by replacing the radial and axial rub-impact module. Shaft vibration response signal
was acquired and analyzed using vibration sensors and analysis system. The relationship between the rub-impact feed，rub-impact struc?
ture，rub-impact materials，rub-impact position and the vibration characteristics was studied，and the typical characteristics and identifica?
tion methods of the rub-impact faults were summarized. |
