Abstract：To investigate the influence of prestress on stress and strain of portable axial flow pump blades, based on the finite element theory, the internal flow field and impeller structure of the axial flow pump were coupled by ANSYS CFX software on the Workbench platform. According to the Reynolds average equation, the flow field calculation was conducted by the SST kω turbulence model. The structural calculation was realized by the dynamic equation of elastic structure, and the deformation and stress distribution of impeller blades under different flow conditions and the modal changes of each order were calculated. The results show that under the actions of water body force and rotating centrifugal force, the maximum deformation of axial flow pump blade occurs at the blade inlet rim, and the deformation degree gradually increases from the hub to the rim radial direction. The stress concentration occurs in the vicinity of impeller pressure surface near the hub, and the maximum stress value of each working condition is much smaller than the maximum tensile stress, which can meet the strength requirement. The prestress has slight effect on the various modes of rotor system, and the variation of modes under different flow conditions is small.
