The elimination of sub-synchronous vibration is a major task of rotating machinery engineers. The industry has used applied imbalance to improve stability of vertical pumps which would otherwise be totally unstable. The current interest is for the application of a small imbalance to determine the influence on the level of instability frequency components for a small high speed turbocharger rotor. The initial experimental results for the application of a known imbalance on the compressor end of a high speed turbocharger, indicates a reduced level for the lower instability mode.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
