NUMERICAL INVESTIGATION OF BLADE DYNAMIC CHARACTERISTICS IN AN AXIAL FLOW PUMP
ABSTRACT
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.
