| Vibration transmission law of aeroengine is one of the research focuses in the industry. By identifying the main path of vibra?
tion energy transmission, structural optimization and parameter design can be conducted to control the vibration transmission of the entire
mechanical system. Firstly, the mechanisms of aeroengine vibration excitation sources and their research progress are introduced. The regu?
lar and irregular vibration sources of aeroengine are systematically discussed, and the rotor system fault research status at home and abroad
is summarized; Secondly, the advantages of the transfer path analysis method and its derivatives, as well as the applications of the transfer
path analysis methods such as TPA（Transfer Path Analysis）, OTPA（Operation Transfer Path Analysis）, OPAX（Operational-XTPA）in
the fields of automobile, subway, ship, and aviation in recent years, are analyzed in detail, and the problems of different transfer path analy?
sis methods are pointed out; Finally, the trend and prospects for research on vibration transmission characteristics of aeroengine are de?
scribed. Since the vibration transmission path analysis method has not been systematically carried out in the field of aeroengine, research
findings about vibration transmission characteristics of aeroengine are classified and summarized, and the vibration transmission analysis
methods applied to the rotor-bearing-casing pylon system are collected and collated to provide a reference for the research of vibration
transmission characteristics of aeroengine. |
