Abstract

The dynamic response for the axial flow pump induced by the fluid excitation is analyzed in this paper. The responses of the axial flow pump during the operation were mostly generated by the fluid excitation and motor excitation. The finite element model was accomplished in this article with consideration of the effect of the fluid excitation and the motor excitation forces. Based on the modal dynamics method, the analysis is carried out to study on the coupling responses under the two excitations. The results show that the vibration source includes the impeller frequency, the axial frequency and the frequency-doubled of the impeller; the response of the motor excitation occupies a leading position in the spectrogram. The research work is meaningful for solving the response induced by the flow excitation of the axial flow pumps.
