Abstract：The axial flow fan,distinguished by its high efficiency and substantial flow rate,emerges as a viable selection for indoor air conditioning applications.Nonetheless,certain categories of axial flow fans could potentially exhibit issues related to noise levels and sound quality during operation.To mitigate these concerns,the employment of a fluid-structure interaction simulation was necessitated for the analysis of stress and deformation in the axial flow fan.The findings revealed a requisite optimization of the blade tip's cross-section,particularly those with significant deformation.Subsequent results indicated that the novel design of the axial flow fan,incorporating reinforced components,substantially diminished the deformation at the blade tip.This effectively led to a reduction in the noise level and the Overall Level difference of the axial flow fan,thereby enhancing its operational efficiency.
