【摘要】：利用Fluent软件对空调室外机的轴流风扇进行仿真分析,分析风扇特征对风扇气动性能的影响,结果表明风扇不光滑表面可以增加吸力面的吸附能力,风扇外缘翻边有利于降低噪声。最后,利用有限元软件对风扇进行模态分析,选择优化方案并进行噪声测试,试验结果与仿真趋势一致。
[Abstract]:The axial flow fan of outdoor air conditioning unit is simulated by using Fluent software, and the influence of fan characteristics on fan aerodynamic performance is analyzed. The results show that the non-smooth surface of fan can increase the adsorption capacity of suction surface. The flanging of the outer edge of the fan helps to reduce the noise. Finally, the finite element software is used for modal analysis of the fan, the optimization scheme is selected and the noise is tested. The experimental results are consistent with the simulation trend.
