Abstract
In order to study the impact of external forces of the influence of the structural characteristics of axial flow blood pump rotor system.Using the blood pump rotor system as the research object,use ANSYS software,Use the method of static structure.the stress and strain analysis nephogram of the blood pump rotor system was obtained under the external load.through the study: The deformation of the blood pump rotor system which under the action of external load was mainly concentrated in the external contact of blade wheel rotor and ceramic shaft,but the deformation is small.So the blood pump rotor system design is reasonable. The vulnerability part of the blood pump rotor system was obtained.it provide date support for the further optimization of the blood pump rotor system and it also lay the foundations for the subsequent dynamic analysis.
