AB - The unsteady numerical simulation of fluid field and structural transient  dynamic analysis of axial flow pump were carried out at three operating  conditions based on fluid-structure interaction method. Numerical results  show that the maximum equivalent stress of impeller occurs at the joint  region of the impeller blade root and the hub, and the maximum deformation of  impeller occurs at the tips of blade leading edges. The frequency-domain of  the maximum equivalent stress and outlet pressure fluctuation of impeller are  mainly affected by the impeller blade passing frequency.
