Study on the Strength of Axial Fan Blades Based on Fluid-Solid Coupling

Abstract:

Based on one-way fluid-solid coupling, a variable pitch axial fan was simulated through ANSYSY Workbench platform. With the software Fluent to describe the flow field and the software Mechanical to describe the structure field, the static structure analysis of the blades was carried out to study the strength of the blades. The flow field data were applied on the blades by interpolation. The results show that the centrifugal force plays an important role on the strength characteristics of the blades. Considering the aerodynamic load, the distribution of stress of the blades tends to be more uneven, the maximum equivalent stress reduces by 4.5% and the maximum deformation decreases by 26.6%. With the increase of flow, the maximum equivalent stress and the maximum total deformation of the blades decrease gradually.
