The article describes an attempt to optimize the flow part of the centrifugal pump by vibroacoustic characteristics, suggests a method of evaluation of these properties by methods of hydrodynamic modeling based on the analysis of force pulsations and moments acting on the rotor and stator of the flow part. The obtained data are decomposed into a spectrum by the Fourier method and presented in the form of dependence of sound pressure level on frequency. By results of optimization, the model with the best vibroacoustic characteristics within the limits of numerical modeling is found.
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.
