This paper analyzes several possible causes of the vibration of a centrifugal compressor impeller, and highlights a relatively new analytical method for impeller vibration, that is localization analysis on Impeller vibra-tion mode. With a solid theoretical basis and precise mathematical formuladerivation, it has been gradually attract-ing attention of researchers, it is also increasingly researched widely and indepth.
