Static Stress and Modal Analysis of the Impeller of the High-Pressure Low-Flow Pump

Abstract:

Based on the design conditions,the structure strength and modal analysis are carried on the impeller by One-way Fluid-structure Interaction technique in ANSYS Workbench platform. The results show that under the water stress, the maximum deformation occurs on the brink of the blade, the maximum equivalent stress occurs at the liner near the blade pressure surface, the deformation of the blade has a great influence on the vibration of the pump.
