| Abstract: | Considering the effect of the deformation of the impeller on the flow field and the aerodynamic force on the deformation and stress of the impeller,the loose coupling method was used to investigate the strength of the impeller with the software CFX to describe the flow field and the software ANSYS to describe the reaction of the structure,both the computational results were shared on the exchanging platform MFX-ANSYS/CFX.The results show that the maximum total deformation occurs in the middle of the blade suction surface,and the maximum equivalent stress occurs in the shroud of the impeller;in different stable conditions,the maximum equivalent stress values are different,but little change. |
